yea, just did mine a couple months ago. would have gone pretty quick if i hadn't taken taken the time to paint it and protect the thing from rusting further.
...never done it before either and felt 10x better after having taken out the stuff that smelled like old diapers

The 8.8 should be 5.5 pints or 2.75 quarts of lube to refill. Probably less depending on how much you are able to drain. If you are adding friction modifier, be sure to add it first while there's still room for it 
(I think I remember not needing it though from an earlier post).

He said his Royal Purple fluid is LS-ready so he shouldn't need to add any friction modifier. I used Redline synthetic which was LS-ready and got no clicks or chatters from the rear end, no FM needed.

The vent is the rubber hose that stems out of the top of the differential and is hung up somewhere near your rear gas tank. This is to allow the rear differential to vent but help prevent it from sucking any contaminates in, by putting it up higher.
