Thanks for linking my videos for the diff shimming, I'm glad they're proving to continually be helpful!

As for the grease, The one little tube in there will usually do 4 or builds for me. The only places I have a significant amount is the ring/pinion gear on the front/read diffs. If you're using grease in the CVDs at the corners, that can use a bit too, but you don't want to overdo it as you don't want it attracting more dirt into there than needed. For the CVDs and dog bone pins, I like to use Cow RCs MooSlick (or any other silicon based spray on and dry), as it doesn't attract all the dust as much, and the dust will more easily blow off since the silicon is dry.
