Bikebandit list the left cover for $134.59, the clutch lever for $18.07, and the bar-end for $42.07.
If it were me, I'd look around at cycle salvage yards for the left cover. Several yards in the states will ship.
For the bar ends and clutch lever, I'd just hit the local cycle shop. Bar-ends and levers are frequently replaced items on motorcycles and are usually in stock at most bike shops.
