what the heck is black ice airfreshener anyway.. in my head.. as corrupt as it may be..
black ice smells like a busted radiator and a leaking gas tank and maybe that stink of airbags that deployed or maybe somethin worse stinkin in the seat

i just assumed it was a cologney smellin air freshener, and i've done that from time to time when Polo or something goes on a big sale
or even better..
if something like vanilla fields (perfume) or be delicious goes on sale, i'll get that
of course that's gotten me in trouble a time or two

but to the original poster:
you can attack the aftermarket thing many many ways
There's alot of stuff out there
You got lifts, most popular around here generally being OME, JBA (jeepinbyal), Frankenlifts (boulderbars), which all range a bit in price but generally speaking.. and the specifics of the price at that point don't make a ton of difference to most people, either your game or it's something you wait till later to do but around 800 bucks will set you right, some are more expensive, and some are cheeper
After a lift, people generally start doing skids and tires/rims , 245-75-16 is a common fitted tire with few rubbing problems that has a good variety of tire choices
skids, you can use Mopar skids depending on their availability, they're generally the cheepest but generally not the strongest by any means, rockyroad, rustys, skidrow, couple others all make aftermarket skids. Biggest advice on skids, SHOP AROUND!! Most of the aftermarket skids are pretty much indestructable, you may be able to find them listed in scratch and dent sections of offroad sites for cheep, mopar wholesalers usually have the best prices on the mopar skids
Rims, some people get whats called a Rubicon rim which I believe is what's on Tommudd's jeep, pretty useful to get the backspacing and such to run them beat rubbers, cragars or rockkrawler like soft8 or d window rims are very common if you go down a rim size to 15x7 4" backspace or 3.75" backspace, or even if you stay with 16x7 but want a new look
Bumpers, I don't know if marty from rocklizardfabrications is still taking bumper orders or not, but that's an option, out of the heavy steel aftermarket bumpers he seems to be on the cheeper side with his budget, but he is soon to take a break to do family so I don't know if he's taking orders anymore
ARB is a common choice on the aftermarket bumpers, exxxxtremely durable, very well built bumper, i think they range from 800-1000 bucks
Some people modify TJ bumpers (wrangler) to fit the liberty, it's a difficult process to securely mount them, but, very rewarding for some, TJ bumpers by far tend to be far cheeper than bumpers specifically made for libertys due to the whole supply and demand thing
If you like lot's of lights and fancy LEDs along the lines .. almost Tuner style stuff, there's LED tail lights that are VERY sweet ICPW? i believe is the brand, they cost just a hair more than if you were to install LED bulbs in the stock tail lights, except the ICPW tail lights don't cause the fast flash commonly experienced with LED bulbs in place of the standard bulbs
There's a LED 3rd brake light too, it's actually pretty cheep, i believe it's around 10 dollars? I think Riptricket has one, may PM him and find out where he got it
There's smoked front turn signals too
Roof racks and baskets or roof rails
Our very own Boiler, makes very sweet Aluminum roof rails and baskets for us, as well as some other aluminum pieces used for front suspension shims to gain a little extra height
there are also baskets that work with the stock rails, blackwidow, safari? i think? and weston, a few others as well
there's not as many choices for rock rails that go inplace of the side steps as we used to have, i know rusty's makes 2 variants, i'm sure there's others you'll come across in your browsing too
there is a mopar brush guard for the front if you're not interested in a steel bumper anytime soon.. i think it looks something like a koala bear though

Most of the bull bars for our jeeps that attach around where the tow hooks in the front go, tend to be just for show and end up damaging your vehicle more than it would have otherwise with very minor front impacts
mopar, hidden and uhaul make rear hitches which become dual purpose, 1, for towing, 2 you can get a hitch insert that's excellent for using with tow straps to pull someone, or be pulled, front tow hooks or a recovery modification in the tow hook section is an excellent idea as well
there's all sorts of weather floor mats you can get, the moulded ones naturally are the best as all the mud/snow/crud you track in will stay in the mat instead of slopping out
performance wise, take your pick of mufflers, it's a choose your poison deal, pretty much anything will be better than the boat size gong of a muffler we get stock, don't know if you've looked under there but its about the same size as your gas tank, except it gets hot instead of empty

Longtalltexan makes a Cold air induction piece that you can hook up some dryer vent hose and route it to your grill to get a fresh supply of cold air to the engine, tends to work better than the K&N style under hood cold air systems that suck hot air
There's hood louvers, again, choose your poison, the raceace.com runcool louvers are popular, but again, within reason, you can make just about anything work, shop around
There's also B&G performance ECM/TCM modifications that rechurch the torque control management on the engine/transmission to allow for higher than stock horsepower/torque and more benefit from added performance equiptment
but it's a pretty penny
thefastman Dan Arcand modifys throttlebodies, hones and bores them out, our stock throttlebodies have a taper to them that restricts the airflow, his tooling on them gets rid of that taper plus some, it works VERY well and it's not too expensive either, the core charge is about half the price
modified heads and cams are available but you're talkin a good bit of bank, with an unequal amount of gain for the money
lockers for the diff's are a great investment, aussie, arb air locker, detroit tru trac are the most common, choices are rather limited with the front diff due to it's design a arb or dtt are pretty much you're choices for the front, you get a few more choices in the rear, either way, gear choices is stock 3.73 or 4.10
rear differential covers are excellent as well
rockcrusher, crane, couple others, the 8.25 chrysler rear end is fairly common, once again, Price Shop!
Well, i feel like im being a motormouth, anyone feel free to pm me on specifics or surf the related section, for example, much of the lighting options are detailed somewhere throughout the electrical section, much of the tires and rims is in the tires and rims section, engine performance tends to be in 4x2, lifts and skids and such tend to be in 4x4, custom stuff that you can do yourself at home, often with very little investment and common hand tools tends to be in the fabrication section
The equipment for the gods tends to be in the SFA section
/motormouth off

edit:
good lord that was a long post
Just for clarification, i didn't intentionally not mention a vendor, tried to get everyone out there, i always like options!
Our aftermarket support, is often a bit Lean.. but it's usually not non-existent, sometimes it's simply just difficult to find
