I took car in to Firestone for Timing belt. Then had to have water pump replaced. Imagine that. I was then told I need the Motor mounts replaced in front. How simple are they to replace and where is it exactly, and where where can I get a diagram to follow instructions. I can do some basic repairs, but don't have a guide to point me in the right direction

Maybe they were talking about the moving control rod. They have to remove this one when they changed your timing belt. Check if the rubber is cracked.

Just removed the bolt on the small rubber circle and the bolt and nut on the big rubber circle. (encircled in red)
