Okay. Rather than write you a novel, I'm gonna link you to some good, informative threads that'll give you an idea of what it takes to mod a Jeep. It's not as easy as throwing on a lift and tires. Not if you wanna keep your rig from spending most of its life in the shop...
This info is from a JK perspective, but the general principles are the same across the Wrangler platform...

Here's a recent thread from a member looking for advice on how to mod his JK. Some fairly basic info in here, in terms of what you can expect to change for a fairly standard 2.5" or 3" + lift.
I have JEEP FEVER....
One last bit of advice: the folks who seem to have the fewest issues modding their Jeeps are the ones who understand exactly what they want, and why they want it. Most of em figure this out through research – and a lot of it.
The best thing you can do is to drive your Jeep stock for a little while...learn what it's good at, and where it lacks. Figure out how YOU think you'll use it. Mud, big-ass rocks, mostly road use? Familiarize yourself with the varioius functions – ESC, HSA, BLD, Anti-stall. Then mod it the way you see fit.
As with anything, the more you put into it, the more you'll get out of it. Trite, but oh so true.
