1. Yes pull the cover, let it drain and completely clean off all the old RTV silicone from both surfaces. Make sure both are spotless clean and no oil residue left on them. Some brake cleaner works wonders here.
2. Get some Ultra Gray RTV silicone, lay a 1/4" bead of it around the diff cover staying to the inside of all the bolt holes. Reinstall cover and snug down the bolts. Some say wait for the RTV to set up before filling with oil...this just never happens in a shop environment and I have never had a leak yet just filling it right away.
3. If you want you can buy a fluid transfer pump/suction gun. Comes in handy for filling diffs and transfer cases. Usually around 20 bucks for one at most parts stores.
4. Spray it out good with some brake cleaner and give it a good wipe out and call it a day.
