No movement?  There should be some, just not a lot.  You should be able to
pull the crank backward by pushing in the clutch, then pull it forward using
the big stick method Harry suggested.

I've never heard of an unbalanced clutch, but I've seen lots of pressure
plates that had little weights welded on them presumably to balance them.

I did exactly what you said and I got no movement. 
This doesn't make sense!  Although a little bit of a relief, I still don't
understand what could be making the rubbing/grinding noise when the clutch
pedal is pushed in.  Also causing rpm drop?  Is it possible that it could be
a T/O bearing or pilot bearing?  I certainly hope so but I doubt it.

I don't know the exact pedal pressure on my clutch but I know a bunch of
people are using the HPF disk with ACT PP.  Also I heard that an unbalanced
clutch could cause crankwalk.  I didn't know shops sold unbalanced clutches
or that it was a good idea to have them balanced but who knows...

I wish I knew of a good shop to take it to in Northern VA, I just don't
trust the ones in my area, not enough Supra experience.

feel free to chime in anyone!

Thanks,
