Welcome to the forum.
Full synthetic gear lube is recommended.
For the gear lube I use 85W-140 in both diffs and the t-case. If I were you I would just top off and then replace it at 100,000 miles and then every 50k after that, unless you do a lot of wading.
I change both diffs on my truck every spring after I go wading.
As far as grease goes, any good automotive grease will work. I use "Green Stuff", you can buy it at AutoZone and Tractor Supply Company.
That driveline slack is normal. The t-case is gear driven and as they wear you get slack.
Grease the u-joints at every oil change.
Check the diffs, transmission and t-case every 6 months.
Any more questions? Everyone on here is more than willing to help.
