If OP can do a 1.5 lift and flat Fenders, caster should be less of an issue even on a two door, as should driveshaft. "Should" as every Jeep is a little different. I would do the lift and then see how it handles and what kind of caster angle there is. If the steering is flighty (symptom of caster issues) then be prepared to address with control arms or drop brackets. But I don't think it should be an issue at 1.5.Fine. 3" lift. 17x9 wheels with 4.5 backspace, and 315/70r17 tires. If you have 3.21 gears plan for 4.88's on a regear. Make sure to correct castor and budget for a front driveshaft.
I'm looking to get into some off-roading here pretty soon but nothing major. Just weekend fun. Most of my driving will be work and back unfortunately. I want the off-road capability when needed while Keeping the on road stanceHa, all wheels are made in China now. Doesn't really matter. If you plan to really off-road, get 17's. 20's are for the street.
Tires, depends on your use. How much off-road do you plan on? Duratrac are great all-rounders. Nitto terra grapplers good for street as well as bfg at. Mud, you want something way more aggressive.
