what do you mean when you say the clutch bell wall might be glazed?

also, I opened the clutch bell and on the inside found a lot of metal shavings. Is this normal? could one of the bearings in the clutch bell be bad?

also, when I now tighten the clutch nut, the clutch bell will not spin without the engine turning over also. If I move the car on the ground it is hard to move it and I can hear the engine make a rotation (that soft puff sound). Should the clutch bell be able to move independently from the engine piston?
