I would definitely recommend adjustable height jack stands. There are quite a couple of places along parts of the suspension which you may want to support. 18 inches should be enough, but then again I cannot know what is comfortable for you. If you want *really* good access you will need a proper lift

I managed to replace my fuel tank using about 18 inch jack stands. That was without taking off the exhaust pipe even. Granted it was *not* comfortable and it was a two people job, but it could be done.
