I just replaced my front drivers side axle seal. It wasnt too bad, just time consuming. As far as the fluid level: I've always been told that you want to be able to stick your finger in the fill hole and the oil should be just touching your finger tip (about 3/4" to 1" down from the fill hole).

You shouldn't have to take the diff cover off, cause the axle will just pull out. That gear oil is fairly expensive. So if you do have to take the cover off for some reason, try to save all you can.
