Clutch is grinding when pedal pushed to the floor and is sticky when it releases.

Just shooting off the hip here. Symptoms make me think the throw out bearing is getting pushed too far forward when you push the clutch pedal, so adjust push rod accordingly. Then, very lightly apply grease to the shaft the throw out bearing rides on, the two points where the clutch fork rides on at the throw out bearing, and the pivot point of the fork at the bell housing. Also, inspect all the clutch related linkages for any interference with other things. You'll need a helper.
