5kcstq clutch, master or slave dead

[Wallace White <whitew@leland.Stanford.EDU>]

A week ago the throw out bearing died on my 5kcstq, so I got a new clutch
in Albuquerque in the middle of my cross-country trip. Then today, I
dropped the car off at a shop here in Nashville, TN, for a wheel balancing
and A/C check (it's a lot hotter here than it was in California!). 
Tonight, I came home to a message that the clutch pedal fell limp to the
floor at the shop. Rats.

I understand that the master and/or slave can die shortly after the clutch
does. That makes sense, given the high force the clutch pedal needed
before the clutch was replaced. So, tomorrow I will scramble to get either
or both cylinders and the hose (thanks to a lister for the part numbers
already), and I really hope to leave Nashville as planned on Sunday
morning.

Any BTDT's on replacing these? I've got the Bentley, though it's sitting
in the car at the shop right now. I may be better off doing it myself,
since I'd rather not repeat last week's experience of a Friday repair
getting delayed and the shop being closed all weekend.

Hopefully my luck will improve for the substantial remainder of my
roadtrip. TIA.
