Mechanic says I need to change motor mounts... Options

[Rider]

1994 GT, Manual, 192k miles

One mechanic told me in April that my transmission mount was cracked. Recently, I've been hearing bumping/knocking noises when accelerating in a straight line that get worse when turning right and disappear when turning left. Also, those "bumps" get louder under harder acceleration (duh).

Went to the mechanic today, and he said to change all of them because changing just one would eventually damage the other two. He also said it'd cost me $480 plus tax - $280 for parts, $200 for labor. Two questions:
1. Is $200 a fair price for labor?
2. The mounts are listed as part numbers 8852, 8869, and 8871, but I've read that I also need to get other parts in order to replace the mounts. I can get those three mounts (Anchor brand) from RockAuto for $133 shipped, but what other parts should I get?

As others have stated man does the rear mount blow - When I had to work on it last, I ended up kneeling both knees on the intake manifold to get the engine low enough to get 1 bolt in....never again. 200 is a fair price for all of them.

Edit:

I probs did it wrong, but it seems it still sucks either way =P

From underneath its pretty damn easy. Head behind the subframe, you have easy access from there.
