About the red powered metal....I'm not sure. I think it's just a mixture of clutch disk dust and flywheel/pressure plate dust combined with the Bay Area moisture.

Clutch materiel is black.
That red is usually unlubed wear, like if you run a CV 2 years after the boot breaks.
I think that shop was probably doing terrible work.
