Also to note 2k miles ago, I got new Goodyear tires from sears put on.

When it comes to transmission mounts ... I have the GM Automatic transmission, do I only need to change the Gearbox rubber mount as shown bellow?
Yes, that's all you need to change for the tranny mount but unless it is actually damaged and/or failed I wouldn't bother changing it.

You need to look into the source of your rough idle before you start throwing parts at it. Could be as simple as an O2 sensor or a rip/crack in your intake boot.

I agree, that the rear trailing arm bushings need to be changed out and that shouldn't take any shop very long if they have the right tool.
