Pressure Plate rattle......

I replaced the throw-out bearing, last summer but not the PP and
clutch disc. The noise is constant whether the clutch is engaged
or disengaged. I checked all the linkage and it is all tight.
I have a feeling that I need to replace everything, I crawled
under neath , while running and it seems to be coming from the
clutch. Should the throw-out bearing spin when it rides on the
pressure plate fingers, or spin only when the clutch is disengaged.
Before I adjusted the pedal the bearing was not spinning at all.
But I did'nt drive it very far . I can deal with the noise but
I sure would like to fix it, I can replace everything, and be
done with it, but the clutch works great and I hate to replace
parts if they don't need it.
