Minimum thickness of the F/R pads is .06" (1/16"); if they're below that, replace. I wouldn't refinish the front or rear disks unless they look gouged or deeply scored; their min. thickness spec is 1.02" (F) and 0.35" (R). Those numbers are from the Service manual, sec. 19. My recommendation on refinishing is from personal experience, FWIW.
