Front diff -- drain from the bottom -- the Torx is a T70 -- fill from the top with a long reach funnel. There's either a copper or steel washer under the bolt.
Rear diff -- is that the one with the plug that has the recessed square fitting? If so, a 1/2 inch drive should work. Those fittings are usually in tight and unless the car is raised, it can be difficult to get enough leverage to break the bond, even with a longer breaker bar. Whatever you do, make sure you loosen the upper fill plug first so you know you will be able to refill, before taking out the lower drain plug.
