Sounds like you're on the right track. If it were me, I'd replace the engine mounts, (upgrading if possible) and replace the pulley and fan. Also!! Check the bearings in the water pump! If that pulley has been wobbling, it has likely damaged the water pump.
Operating the clutch changes the vibration. That indicates to me that it may be shifting the engine on its mounts, it's moving the crankshaft in the engine forward, which could mean internal engine issues,or you COULD have an issue in the transmission! Does the vibration change much from the lower gears to high gear?
