I have a peugot 206 roland garros v reg year 99

Within thelast week my clutch has been playing up, first when I pressed the clutch pedal their was a noise like a slight crunch then I heard another noise like grinding metal on another day when at idle and when I pressed the clutch in, then I felt the clutch pedal slightly move as I was driving, then the clutch pedal was shaking up and down then when I tried to drive it the pedal just released and dont engage and is freely moving up and down, their was also alot of steam coming from the engine, I didnt start it for 2 days then when I did it wouldnt start at first but when it did it sounded really rough and loud, I have brought a new clutch to have fitted but have I done more damage to other parts by driving it, I have read things about the flywheel could you give me some advice as to what I mightve done and to what parts have I ruined it completly
