How clean is clean enough for the head gasket block surface?

The pitting is of no concern there. That area is open to coolant via the water passage in the head. I would not do anything with it.
Deck looks great. Cleaner than most of mine when I do them.
Pistons, leave em be. You're likely to do more harm than good by breaking schmoo free that will find it's way between the piston and piston wall which could cause scoring.

Spray-on oven cleaner is great for cleaning combustion chambers, including the piston crowns. Just don't leave it on very long because it will start to erode the alumnium.
Clean each piston when it's at TDC, then rotate the engine to do a another one. There will usually be a small debris ring on the cylinder wall after you clean the crown, so wipe that away before that piston comes to the apex again. Wipe everything down -- including the decks of the block -- with a lightly oiled rag after you're finished.
