I just changed all my fluids in my truck, a 76k20 with the 465/205 combo.
I do not have the exact axles you have - i have a dana44 8-lug and a 14bolt FF. However, they took about (just guessing here since I got a 35lb container of 80w90 and use a squeeze bottle) about 4 quarts front and 6 quarts rear. In case anyone is interested, the 205 took about 5 and the sm465 (4-speed stick) took a whopping 7 or 8! All my stuff uses 80w90 gear oil. You axles should too, but your tranny since it is auto uses some sort of ATF, not sure what. Your tcase with a 700 is a NP208, right? I'd guess it uses 80w90 also, but check with some else to be sure.
Make sure you put in some friction modifier if you have a LSD in the rear or you will burn it up.

BTW, I found out the 208 uses regular motor oil (like 10w30) not gear oil. It uses it because it is chain drive.
Just to let you know.
