I just picked up a 2005 Liberty CRD Limited last night. BTW, it has 36,000 miles on it.

So far I've just driven it home and around town a bit, but I love it.
I have been reading up on all the issues/upgrades and was just looking for some advice on what to do first?
The first thing I plan to do is change the oil. Obviously, since this is my first diesel, please excuse my ignorance, but do I need anything other than the oil and filter?
What about a Provent? Should this be high on my list as well? Is there a good parts list and or how-to thread?
How about the tranny fluid and filter?
Finally, I am going to be needing tires soon... How long are the stockers supposed to be good for? For now I will be staying unlifted, so any recommendations on stock replacements?
Welcome, and congradulations on the CRD purchase.
What to do first? Research the warranty and maintenance history on your Jeep (a dealer might be willing to run the VIN# for you). Look under the hood for tell-tale signs of updates such as TSB stickers. You need this baseline to know what to do next.
Second, look for chronic issues that a dealer may have called "normal" such as oil in the Charged Air Cooling as an example. And the answer to adding a Provent is yes (or open vent).
Third, dig into your owners manual for maintenance recommendations. A 36K miles, if that trans hasn't been serviced it should be done given the track record of failures when connected to a CRD. Personally wouldn't push the oil change intervals much past 6K miles given the soot loading from the EGR engine. Best to use a quality CI-4/CI-4+ rated 5W40 synthetic diesel engine oil with a premium filter.
Finally, research this forum for the clasic CRD problems. Many cases the fixes are stupid simple and will save you a lot of aggrevation.
