[s-cars] S6 drive line issues

[Rokas Reipa]

Hey gang. Two(ok, maybe three) issues that I need help resolving on my 95.5
S6
1) Clutch pedal recently began vibrating ever so slightly when engaged(pedal
to the floor, about to accelerate in first). Clutch action also has gotten
much lighter. What does this signify?
2) When the car is cold, there is a significant wobble from what feels like
the right front side. Manifests itself above 30mph and continues onto
highway speeds. Lessens and almost disappears when car warms up. What could
this be?
3) When shifting from second into third and third into fourth, there is a
clunk emanating from the rear of the car, right as the clutch engages. What
in the world..?

Please help...

Thanks,

Rokas
