by polish the crankshaft, do you mean doing like a wet sand with high grit sandpaper on the parts the rest inside the bearings?

You'll need PL-X Plastigage. For measurements of 0.018mm - 0.045mm. (0.0007 in. - 0.0017 in.) Yes, if the tolerances are off you'll need a set of bearings. However, that's unlikely but still possible. Don't forget to measure the side play of the crank in the cases too!! 0.002-0.008 inches.
Typically done with some emery cloth, leaving light score marks on the crank and getting rid of any wear or high spots. Kind of like a brake rotor, just a light scuffing to provide a new mating surface. The emery cloth comes in skinny strips that fit very well on the crank surface.
