I don't think you really need to remove the rear engine mount, actually transmission mount, but the exhaust system will have to be dropped.

And when you have the driveshaft out be sure to mark the two halfs with a line of some sort so it can be reassembled in the same way. These are balanced at the factory as a unit and if you get it out of sync you will get a lot of vibration.

And marking the front and rear with a piece of chalk or a strip of tape is easy.

Be careful not to knock off any of the balance weights. I have seen these attached to the driveshaft in two ways: Spot welded, sometimes called tap welded, and just glued on. If you knock one off then pick it up and glue it back on with the strongest glue you can find. Then clamp it down and let the glue set. These weights are small squares applied here and there.

One way to speed this up is to have a helper or two. This comes out easy, it can be tough to line back up.

But all it in it is rather simple.
