no, you want more BS to keep the wheels in more. pushing them out means they need more room to move around in your wheel well.
now, for lifting, look into Doetsch spindles, a 2" lift block and a 2" shackle. this will give you a small rake, and it looks killer. get some 3-4" lift shocks for the back, and your done! none of those will hurt your truck. Doetsch is IMHO the #1 maker of spindles. they are less then fabtech or pro-comp, they are stronger, and they are better made. I have had mine for almost a year now, and love em.
now gearing with 33's, if you have a 4.0L, do 4.56's. if you have anything smaller, 3L or 4cylinder, get 4.88's.
