I really like the Wiseco bottom end gasket kit. It comes with all of the seals and gaskets for the bottom end for about $40. Their crank bearing kit is also a good deal. Koyo bearings in a Wiseco box. Go to Vito's for the rod kit. Best deal on rods and I've never seen one break. Pro-x rods are great but a bit more expensive. Stay away from Wiseco rods and crank kits. Just get the stock crankshaft rebuilt. Use Yamaha for the top end gaskets and transmission bearings.
