I never use a differential cover gasket, just RTV. Check and make sure the differential vent isn't stopped up. If your spider gear cross pin has a bolt and not a pin holding it in, be careful not to snap the bolt off. Tap the end of the bolt with a hammer and remove with feeling, force can cause you all sorts of grief. The cross pin bolt snapping off has caused many a people a lot of grief.

I personally like to use gasket and alittle RTV. It cost alittle more but I feel better about it not leaking but as said already alot of people just use RTV with no problems. The gasket at Advance Auto is going to run you $10.

rent a bearing puller aka slide hammer which makes it easier to remove the bearings instead of bending up the tubes using a punch and a sledge.

get yourself a lubelocker gasket for the 8.25 diff. You can re-use it each time and never have to deal with RTV

I squirt some gear oil onto the bearing and coat the seal lip with GO 90, so they positively don't run/turn dry at any time. I usually lube them after installation and before replacing the axle shafts, to avoid some mess. I have used grease instead of gear oil on occasion. Most of the gear oil bottles have a squirt tip, which makes giving them a bath easy.
