Don't know whose jeep you drove set up like that, but I have to disagree with you.
I went with 33's and 3.5" lift (kit said 4", but really it's only 3.5"), and I needed a body lift to help clear the tires. Even then, at full stuff, the tires still rub. Time for some longer stops.
And with a 4.0 you can get away without regearing if you have 3.73's
Again, I will disagree with you. I re-geared to 4.10s and 33s, and curse the day I made the decision to only go with 4.10s. I've seen guys run 33s with stock 3.73 gearing, but the highway performance simply sucks. However, if you have the standard (not the auto), maybe the 3.73s are OK. If you decide to go with a change of gearing, Listen to what Greg said, and go for at least the 4.56 gears. I would say strongly consider 4.88s, but at a min, go for the 4.56.
Whenever you make a change in rear end gearing, tire size or any combination, you simply have to go to the local Jeep dealership and order the correct speedo gear. They only cost about $10, so it is an easy and cheap way to counter the other driveline changes you have made.
Here's my disclaimer for the rest of my post: Make your decisions on what you purchase on the percentage of on-road to off-road driving you do. My rig seldom sees on-road driving. If you only plan on driving easy trails, gravel roads, etc. Maybe you can get away with cheap....However, also think ahead. After only one year, I'm in the process of putting together more lift with a longarm kit.
As far as lifts go, don't do what I did. I bought the cheapest 4" lift kit on the market. It works well, and some of the guys on this board have seen it work. I think they will say it works pretty well. However, you get what you pay for. I've learned a lot since I built this version of my rig. If you decide a short arm kit is what you want, look closely at the joints used in the control arms. Rubicon Express makes nice joints on their super flex kits, Johnnie Joints are excellent joints. Poly bushings work ok, but really put stress on your control arm mounts (just ask me, I broke one recently). Make sure the control arms are adjustable for pinion angle. This will help when it comes time to decide whether you are going to shell out for a SYE kit. Which I suggest for any lift over 2". T-case lowering kits are like band-aids.
I really suggest just going with a long arm kit, but again, base your decisions on what type of driving you plan on doing.
Good luck with your decisions, and let us know what you decide.
