That'd be "For The Win".
Always cheaper and more rewarding doing it yourself. Lots of good, useful pics in your post.
So I'm curious as to whether a simple replacement of the faulty clutch disc (and a thorough cleaning) solved your problem (if you've gotten that far) and if no other clutch components needed attention - aside from the slight slave cylinder leak you mentioned? Any idea what caused the friction material to separate and shred like that? Was the disc nearing the end of its useful life?
