I'm concerned I may have ruined my clutch.

Here's the evidence:

1) Rotating noise, only when car is moving. Intermittent, but most often between 1000-2000rpm. Often goes away when clutch pedal is depressed. Seems to be exacerbated by bumps in the road, which I found weird.

2) In 3rd and 4th on the highway, car runs too quickly to redline without the same pull as typically in 2nd gear.

3) I recently replaced the heater control valve with a metal one - it had been leaking. I'm concerned it dripped on the clutch, causing a failure.

Could I tell anything by looking in the clutch inspection window ?
