What's wrong with the current diff?
You have a pretty good grasp...Remove diff cover, pull the small bolt on the cross pin, remove the cross pin, push in on the axle shaft enough to remove the C-clips and slide the axle shafts out. Mark the carrier bearing caps with a punch and keep all the shims together (I use a zip lock bag for each side so nothing gets mixed up) since you are reusing your ring gear and not changing the pinion depth, it all should go back together and be pretty close the the original specs, use the bearings and races that came with the open diff so the wear patterns on the bearing and races match. If you have trouble getting the carrier out, put a box end wrench on one of the ring gear bolts and rotate the pinion until the ring gear walks it self out. Depending on how many miles it has it might just fall out, but it should be tight, that's what preloads the carrier bearings. Get a dial indicator to check the backlash, should be .006-.010" then double check the pattern with marking compound. If you don't have a dial indicator, you might be able to borrow/rent/buy from an auto parts store. HF tools has them for cheap, too. A micrometer or calipers would be good to measure shims with in case you need to swap a few to get the back lash just right.
Randy's Ring and pinion had a great set of instructions on his website. http://www.ring-pinion.com/downloads/yukoninstman.pdf
Hope that helps
