Jeeps Canada - Jeep Forums - Just picked up a cherokee. new to 4x4

Hows it going, i just bought a 1999 Cherokee sport 4l. it has 189,000km on. so far i have been using it as my daily. the jeep is in immaculate condition. runs strong, slight wobble at high speeds. pretty sure it just needs an alignment and balanced wheels. as i said in the title i am new to 4x4. i love working on my vehicles, and i would love to do something with this jeep. to give you a rough idea i'm looking at a 3' lift with maybe 31' tires. i was looking at the rough country lift kit, what are your thoughts on this brand. and what the heck else do i need because as ive seen from working on other cars, one modification always seems to lead to another. i would like to keep it as a daily driver, but i would also like to take it through some mud holes obviously. (who wouldn't). the problem is i have no idea where to start. i would like to strengthen the steering components, and maybe some locking differentials. ive always had European type small cars, and i am new to the Chrysler family. i have done some research online and everything i see is different. if you guys could give me some tips on a basic build, i will supply you with pictures and the satisfaction that you helped me build a mud machine! thanks for your time.

PS i see everywhere people saying to wheel before you mod. which i have done. i got it stuck. so stuck a huge lifted bronco got stuck and broke a drive shaft pulling me out. luckily the local farmer was nice enough to help us out with the ol j deer. and ive also taken it on some minor trails. so much fun, but i need more.
