Yes to bleed the clutch there is a small nut with a spout on it (the bleeder valve) that you loosen right at the quick-connect on the transmission bellhousing. This is best done with 2 people, one watching and controlling the bleeder valve, and the other to push and raise the clutch. While the valve is open, push the clutch in (it will probably fall right to the floor and not come back up). You should see some fluid and maybe air bubbles comming out the bleeder. Now close the valve, and raise the clutch back up to its normal position (this may have to be done by hand). Open the valve and repeat until there are no more air bubbles comming out the bleeder valve. Pump the clutch several more times and it should return to its normal stiffness and feeling. You might need to top up the brake fluid after this procedure depending on how much was lost (the hydraulic clutch shares its fluid with the brakes).
