Welcome to the addiction! I see you already have a few diesels in your stable.
If you have not read through Sam's NOOB guide, you should do so, it will provide you with a lot of very good information on this unique vehicle.
Other things to consider as time and money allows:
Below is a list supplied to a couple of other requester's on here previously, it is not all inclusive, but a good basic list of possibilities to consider... Searching on this forum, you can find informational threads on most all of these items along with the 'how to' instructions... Have any questions on any of them just ask, there are many great people on this forum more than willing to help and answer any question no matter now trivial....
**Timing belt replacement should be number one if you have not done it or know if and / or when it was last done! Most replace the water pump as well when replacing the timing belt...this is an
Interference Engine. Loss or slippage of a timing belt can and will cause internal engine damage including broken rocker arms, broken or bent valves, and sometime catastrophic engine failure. So it is not something to be ignored.
Broken or slipped timing belt repairs can get
very expensive when considering replacement costs of damaged parts and labor...
Some good updates and mods worth considering as time and monies allow:

1. **Replace timing belt /water pump (read above)
2. Install In-tank fuel pump (eliminates all air in fuel problems)> http://www.auerbach.ca/kj/lift_pump/
3. Install ProVent on CCV system (gets the oil out of the turbo inlet hose, turbo, boost hoses, and CAC)
4. Install Secondary 2 micron fuel filter (protects expensive CP3 fuel injection pump and expensive fuel injectors)> viewtopic.php?f=98&t=80139&hilit
5. Install Silicone Boots Hoses
6. *Install Weeks elbow kit (removes EGR, EGR cooler, and FCV) > https://shop.sasquatchparts.com/product ... berty-crd/ See item #8
7. Upgrade torque converter to Hemi or SunCoast TC (solves and TC shudder issues if installing performance tunes)
8. DIY performance TUNE ($0 cost and available on this list in the CRD Tech section) > viewtopic.php?f=98&t=78418
......{a must do if you install the Weeks elbow kit to eliminate DTC's (check engine light) that will be present when you remove the EGR & FCV)
9. *Remove CAT & choke point and put in straight piece of pipe (improves exhaust gas flow, lowers backpressure on turbo and improves turbo spool up response time)
10. *Replace muffler with straight through performance muffler (same improvements as item #9)
11. Rear shocks (You did not mention replacing them in your post!) {upgrade tires if needed}
12. Check / replace upper and lower ball joints if needed, they wear out and can separate
13. Service transmission, replace filters & fluid (use only ATF+4 transmission fluid)
14. Install Magnefine in-line transmission fluid filter (filters and traps all micro fine metal particles and can be serviced without dropping transmission pan)> http://magnefinefilters.com/Magnefine-3 ... -R038M.htm
15. Change engine oil / filter (install larger better quality filter)
16. Replace: engine head bolts with ARP studs, rockers arms, and exhaust valves (ex. valves can break) {proactive engine failure prevention}
*Removal of the CAT and EGR valve totally may not be possible depending on your location and whether or not your vehicle has to endure an inspection. If it does there are some workarounds for both items to disable them completely but leave them in place for visual inspections purposes!
