The part numbers are different, as well as the cost of each.

what they call them is confusing. to simplify, you have a trans mount that goes under the trans side pan by the left inner fender. you have a motor mount at the front of the engine under the crankshaft pulley. and you have 2 torque struts on top that goes from the engine to the top radiator support by way of a bracket for each. I just changed my trans mount and I think it'* pretty much the same as yours. I jacked up the car, put it on jack stands, removed tire and inner fender well (I don't know if you need to remove it, I was doing other repairs and had it off) Put a 2 by 6 board that covered the whole under side of the trans pan. jacked it up until it just had some pressure on the pan. then removed all 4 nuts. very slowly jacked up the engine until the mount had enough room to come out and that was it, I didn't have to take anything else loose but check as you go. It only had to go up a matter of inches. don't know about the front one, but it may come out the same way. hope this helps.

Hey William, I'm seeing different motor mounts on different gm websites. you will need to go by your options code. It may have something to do with it being supercharged or not.
I use Wholesale GM Parts Online, GM Parts Direct and GM Parts Giant.

Wanted to update this...
I finally decided to replace my front calipers, and when I did I noticed that it looks like all the rubber is gone from my driver side control arm.
Replaced calipers and the vibration at breaking is gone.
So I do not believe my trans and motor mounts are bad.

The rubber looks tired, but it looks like it'* mostly there, right?

All I see on that top part is hard plastic, I did not look at the underside, but the side in the picture does not have any rubber.

So this part is hard plastic, not rubber?:
