Welcome to the forum brother.
With 35's on your YJ you have to think about a new rear axle. Unless you plan on keeping it on the pavement and even then....the D35 likes to break with 35's.
Have you checked out the "YJ lift review" section at the top of the YJ section yet? It can give you an Idea of what you will need to run 35's and the intel on differnent lifts for your YJ.
Personally for 35 on your jeep I would be looking into a Spring over lift.
