Unless you build up your axles (chromo shafts and tube/truss) when you regear then the smart thing to do is to stick with 33s. Even with 33s your going to want to add a steering box brace to your list as it is prone to ripping itself off the frame/unibody once larger tires are installed. To run 35s and 3 inches of lift you would have to open up your fenders ALOT. Your still going to have to do some trimming with 33s and 3 inches of lift. Also pretty much everywhere 35s will take you, 33s will get you there also.
