As far as the bearings go, I agree with the above. As far as the cam and crank go, I am not sure if the "best" is what you really want. I run a LAE billet steel crank in my car but it cost $3000. I would go with something like Eagle. A 4340 forged Eagle crank will handle alot of power. If you are interested in a LAE crank, there is a site below that sells them. As far as cams go, I have always been pleased with Comp Cams.
