with that amount of lift, 35's will be good, look for a 10" wheel width with 3.5" back space this will allow the 35's to mount without side wall pooch. As far as finder trimming you're probably going to find you need some. Steve has the money figures and I would think just the lift should only be around 10 hours tops at an equipped shop that knows what they are doing. If your planning to swap out the axles, you might want to wait on the gear change and have that done to the new ones before you mount them up. why pay for two gear changes? on the other hand the 8.25 corporate is a pretty good axle strength wise, nearly as strong as a D44. still, it's your money in the end. Steve correct me if I'm wrong here.
