Well I've been really pressed for time lately so I didn't get to the engine mount until a few days ago and I have yet to do the trans mount. The engine mount was definitely toast, totally destroyed. There was actually a pretty large hole in the side of the mount and all the fluid ran out. The engine bracket was resting/bouncing off the metal stud in between the two rubber "humps" of the top part of the mount. This was producing a noise similar to a bad strut mount and I had mistaken that sound for a suspension problem. It had impacted frequently enough in this way that part of the stud was flattened, not round.

The result is dramatically reduced vibration. The engine movement is still somewhat present, but only because the trans mount still has to be done. I've got the new trans side mount too but I have to wait til Friday.
Some issues I ran into:
When raising the engine using a 2x4 and hydraulic floor jack the passenger side CV joint was being stressed to its limits, at one point I heard a soft "pop" and saw the boot around the joint shift very quickly. I was pretty sure I destroyed the joint but it's been a few days and it is apparently completely unharmed. I even drove it on the highway several times. Definitely should have jacked up the hub.
When lowering the engine, the engine bracket was not lining back up with the two studs on the new mount, so I had two friends help me from above to guide the engine (by hand). Obviously this is very difficult to do by your lonesome, I tried for 20 minutes. With two people helping me we did it in 30 seconds.
