If comfort is really important then don't lift it. The ride will stifen quite a bit. A stock Jeep will do what you want. Now if you want looks, a standard is the 3" lift with 33x12.50 BFG ATs. You do NOT need any mods to the tranny for this. Again if you are not doing a lot of off roading (meaing serious off roading) the big tires are going to add a ton of noise on the streets.
I had an 88 Wrangler for a few years, lifted it and it was fun for a while. The noise, stiff ride and shitty gas mileage got to me. Plus shit like the speedometer will be wrong, and actual mileage will be off.
Again, if you're not in competetions or doing some extreme 4x4, then leave it stock. They are designed to be 4x4's and the mods are mostly for show/hobby/competitions.
