This sounds exactly like what happened to my MGB 3 years ago.
> Sudden onset of problems, no related problems before. Vibration
> felt through clutch pedal. Car seems to drive fine in any gear

> Engine slows down and eventually stalls with the clutch pedal

> Clutch fluid, Gearbox oil, engine oil levels all normal.
There was occasionally a loud screeching sound when I pressed the
clutch in.

In my case it was the graphite thowout bearing. The graphite
shattered, throwing the pieces all around. My throwout bearing was
reduced to it's metal shell. Of course, I was on backroads in
northeastern Pennsylvania at the time, driving to Virginia. The
interstate had gotten dull. The good news was I made it home without
a problem, although I was quite anxious the whole time. I did not
find out what the problem was until I pulled the engine. The clutch
was worn out (it had 90K miles), but the throwout bearing did not seem
like it should have been worn, based on comparing what was left with
a new one. The metal at the back was about to wear through from me
using it for 250 miles.
I have no idea what brand of t/o bearing it was, as it was installed
my the PO.

Sorry. I know you can do fix this in a weekend though, 'cause I did.
