With the sprocket spinning that fast without the engine running and oil flowing could it damage the clutch or engine? Should I put extra grease on the clutch or anywhere else?
As long as your chain alignment and tension are good, coasting with the clutch disengaged won't hurt anything. When the clutch is disengaged the only moving parts of the engine is the drive sprocket and the clutch cross shaft. The crankshaft, piston and the gears on the right side don't move. Of course you need to assure that when you pull the clutch lever in and lock it that it is completely disengaging the clutch. That's part of clutch cable adjustment.
There's no need for extra lubrication but the chain does need it, coasting, pedaling or under engine power the chain needs lube.
