Hopefully someone will correct me if I am wrong, but I believe you put ATF in both the tranny and the TOD. The gasket goes on the pan that you drop, and iirc, there is only one pan to drop. The drain/fill area is not dropped.
I would say Mobile-1 and Royal Purple are your best products. Mobile-1 is much easier to find, so I would go with that, plus it is typically about $1-$2 cheaper than the RP.
I would say to be safe, pick up 8-9 quarts of ATF. I know I still have 2 full quarts in my garage from when I did mine a year ago. I don't know how much for the diffs or if they need different types.
