Tapping sound and shattering clutches is not a good sign.

Tapping could be any of your bearings failing and the shattered clutch could be from a warped flywheel or from bad main bearings so the crank is moving up and down and the tranny input shaft is trying to hold the clutch disk in 1 position when the crank is pulling it another way.

I would take and put pressure on the harmonic balancer and while doing that have someone step on the clutch, if the crank moves any noticable amount your bearings are fucked.
