Another new guy here like the OP, I came here to learn and for advice. To the OP I'd suggest doing a good amount of your own research, a lot of the info you are looking for is here but you need to take time and find it. You'll get a lot more help if you make some effort to research then ask for answers to things you don't understand. I'm just as clueless as the next guy but I've learned a lot by reading through build threads and getting ideas for my build. I'll probably come up with a list of questions to ask here before I start with mods, or at least post up what I'm thinking of doing and ask for opinions. Just tyring to help since I'm in a similar situation, but note that with the small amount of research I've done, I can tell you're asking a lot when you say "what do I need to run 35's on a stock TJ". From what I can tell, if you have to ask that question then you don't have any business trying to run 35's. I'd suggest doing what most of these guys are pushing you towards and trying to do something on 33's.
