Dan,

I am trying to diagnose my own clutch problems, but here is what I would try.

1) Make sure that the system is properly bled.
2) If it is I would suspect the throwout bearing and/or pressure plate due to
the noise you were hearing.

The cable was added on later Spitfires as a safety measure to keep the engine in
the car in an accident.  It is called an engine restraint cable.  If you have
the Bently manual it is shown on page 157 or page 26 of the TRF catalog.
