Ok, update 3:
Well, the vibrations from last night are gone. Car is even smoother than before. I noticed that I CAN SEE CLEARLY IN MY MIRRORS!!!!! They aren't vibrating at all! The idle-1100rpm vibe is still there, but even less. Above ~1300 the car is as smooth as stock, but still has the more solid feel of the mounts.
Girth, the mounts are supposed to have the metal insert. That is to locate everything properly. To remove the bushings, hammer the insert out first, with a socket or extension. The bushings *should* come out easily after that is removed. Intall will be the reverse, but the bushings in, then the metal insert.
