I have done more that a few rear setups, I would have to say that, gear mesh/footprint are the most important factors when setting up your rearend. Getting your "footprint" as close to center is most critical, closely followed by gear backlash. both are of course are set by shims. Footprint is set by Pinion shims, where as backlash is set by carrier shims. Don't get to caught up in the math, as long as you have those two right you can't go wrong. I like REDLINE 75W90 for my steed.
