1998 Ford F-150 clutch pressure plate found black fibers?

I took my 5 speed transmission out of a 1998 F150. Then looked at the pressure plate, and there were black fibers hanging off of it, I've gotten quite a bit out by now. I'd say about a golf ball size worth. Was wearing gloves because I know it's harmful to your body, that is, if it's the clutch dust. First off, are these fibers from the clutch? Second, Could the slave cylinder leaking(without boot) make my clutch wear faster? Haven't taken the clutch off yet, but these fibers seem to be tell-tale sign to replace the clutch and slave cylinder.
