80/90 would be correct, but you could use a synthetic that was different than that without issue. They don't care a bunch really.
Make sure you use a limited slip additive if you have a sure grip, regardless of whether the oil says you need it or not. It won't hurt anything, and it might chatter without it.

Regarding "how much"....
I get a gallon along with the hand pump. I just fill it until it starts to seep from the fill hole. Its usually around 2 1/2 quarts. A wide C body will take more than a narrowed A body housing. ALSO, make sure that the car is sitting level or close to it.
