Regarding the piston, unless there is a sharp burr or other deformation on the surface, I'd leave it alone. If some spot does require attention, do the very least work necessary to allow the piece to slide freely in the bore.

I don't know the significance of the mark on the gear but doubt it has any significance to performance.
