I fill the diff with oil up to the point the small gears are completely covered. Then I rotate the outdrive so the gears all turn and the oil works to all areas of the diff. Then I add oil till again the small gears are covered. Repeat until the small gears remain covered after turning (you'll have to push the axles down after rotating as the gears come up in the oil).
Getting a bit of oil out of the screw holes is fine.
