Nice Jeep! I suggest going with a smaller lift if it's your daily driver. I went with the 2.5" Skyjacker because anything under 3" usually doesnt give much trouble in the way of drivetrain. That being said, if you have the money to go higher and get bigger tires then do it. The only reason I haven't yet is that I can't afford the part to fix the changes to the drivetrain (higher lift changes the angle of the drive shaft, also gets into control arms witch usually come with a lift kit but make the kit cost more). You can still run 33" tires on 2.5"-3" of lift too. I'm planning on adding a body lift to mine and from my understanding body lifts dont have nearly the same effects on drivetrain that big suspension lifts do (although i might have to do more research on them). In the end, the overall lift is higher with bigger tires and the new suspension anyway. I did have to have my U-joint replaced but that was because it came from the factory phased and I just hadn't noticed. Also, get quick-disconnects cause the first thing your gonna want to do is flex and I really regret replacing my sway bar connects with new stock ones.
Thats just what i've learned from this site, and one other important thing is that if your not willing to or cant afford to pay for repairs or parts, then just leave it stock. This member's threads might help you, they certainly helped me understand a whole lot about running big lifts and big tires: (Go to his Forum Signature section on his profile)
EDIT: Another thing I learned about from this site is Gear ratio and axles. You need a higher gear ratio to turn bigger tires, this means you have to replace the ring and pinion in the axle. You wont have to do this for 33's but any bigger and you might find you need them. Most Jeeps have a Dana 30 in the front and a Dana 35 in the rear. These axles become to weak with a lot of lift and big tires, most people on here swap to D44's from what I've seen. Again, you probably wont have to do any of this but just keep it in mind.
