Like you I'm doing a lot of reading and trying to get a better understanding. Your 4.10's give you a lot of options though. From what I've been reading going to the 33" won't be a huge impact and would need only a 2" lift for clearance, you'll need more like a 2.5" lift for the 35" the 35's also impact your speedometer as the Jeep computer can only be adjusted up to 28s. - I've got the 18" wheels which is my limiting factor but I'm looking at going to 33" and new 17" rims.
