Your going to find, that there is a big difference in a 2", and three 3". Three inch lift are going to typically, much like the Full Traction, give you a little more. But what i found with the 2", its really just make the jeep look a little more stout. With a 3", (im not knocking anybody with 2" lift...PROMISE!), I find your starting to get a little more usablity off road out of your rig.
With my 3", personally, i feel very solid on the road, and very secure off road. Even with the 285's, (being eleven and a half inches wide), there is a sense of great stability.
I would not put 33's on a 2". Im actually, looking to take my lift a step better, and get adj. control arms, and put some taller springs. My 33's fit wonderful, and they are the perfect size for the lift. However my 33's, much like a lot of other forum users, will easily accomodate a 4" lift.
3", is a minimal for 33's. imho
