Wowee! thats a lot of upgrades for a new guy LOL
I think the best advise I've heard is to wheel it first, then decide on order of upgrade
All depends on what you have planned to run, Mud/trails or Rocks ??
Also, the first thing I would do is find a local Jeep club to join, wrenching with others and and meeting with other on group trail rides is the BEST part of the community IMO. Another bonus is that you get a chance to discover the areas you can legally wheel in your area
I'll let others comment on your parts list.
Welcome and have fun!!
