Clutch problem

I drive a 1999 honda civic lx 1.6 SOHC with a 5 spd manual transmission. I was driving down a hill when I downshifted and heard a pop, and the clutch pedal went and stayed on the floor, and I can put it in any gear without the clutch, like it is stuck. I towed it home and tried to pull it back and now it stays in its normal position, but there is nothing there until the last inch or so. If I put it in gear and start it it seems like it wants to go a little even when I have the clutch pushed in. And with it in gear when I push the cluth a weird sound comes from the tranny. I checked the fluid and it is full. I have been told through out bearing, and pressure plate. I have little experience with mannual transmissions. Any help would be appreciated. If you need any more info let me know
