If the pedals to the floor you'll need either Clutch slave cylinder or clutch master cylinder or possibly both. If you're slave cylinder was failing, it could cause you to burn the clutch, but the clutch may have life left in it, and would cost significantly more for a shop to replace than just a slave or master cylinder. Get the slave working before you decide to replace the clutch, since you'll have to pull the tranny out to do that
