Just watch it till you see how to take off the front end to access the front diff.

Everything else is easy. The little shims that people talk about are located between the little square pin holders and the planetary gears and they're REALLY little and like to stick to things and get lost. Just pay attention to those and you'll be fine.

You don't need anything but diff oil, some type of sticky grease, and some type of cleaning agent to clean out the old grease (I like nitro clean that you can get at a hobby shop).
