oil pump rebuild questions

Rebuilding my oil pump for the 1951 288, and came up with a few little questions.

Does this dimple on the driven gear mean anything, should it be facing in or out from the pump? See picture with red arrow. My guess is that it is 'vollig wurst' totally sausage hehe.

Also, the pressure relief piston...it feels smooth, but looks a little rough. Here are some pictures. Should I try and make it look nicer with crocus cloth? -whatever crocus colth is...

I've never used crocus cloth, but can get some 1200 grit or finer something (not sandpaper) at a hardware store here I guess.

Thanks guys.
