Honestly I have no idea what I use, like 40? Pretty rough.
When you get it resurfaced, it's turned or ground, similar to getting rotors turned, providing an entirely new, perfectly level surface. The DA is more like a hone, to hopefully give something better to bite to and break in against, without removing a whole lot of metal. If it's parts that were all used together, you don't need to, if there's no irregularity or damage.
That sort of thing is specified in some service manuals before re-assembly of undamaged parts, but if it's out because of chatter or something, it would be proper to have it resurfaced or replaced.
Judging from that disc, you don't have a lot to worry about.
