Ah, but what shape are the strut bearings in?? I bet they are in need of
replacement. Some of the symptoms you described are direct indicators of
the strut bearings going bad, which, doesn't take long for them to
degrade to a worthless hump of rubber. Usually people notice them when
the bearings are hammered and are making clanking noises while comming
down the street that they live on.

What about the rear tranny mount?? That one might seem like its ok, but
it's not. The rubber in them get really soft and transmit alot of
vibrations into the chassis. Its also the closest mount to the steering
rack. That could be the reason for some of the steering wheel vibration.

There are rubber mounts that hold the steering rack to the chassis. I
think these are worth looking at for possible replacement.

I dunno. sorry.

These will be bad if you have lateral play in the steering wheel.
(Movement left and right ect.) usually these bearings simply fall out at
the bottom and this is the reason for the play. 
HTH!!
