Is that back water jacket clean enough too?
ALSO, ...so many questions... should I bother cleaning the tops of the pistons? Or just leave em?

The pitting is a little concerning. You can tell water was making it's way under the gasket, I'd be concerned with it trying to get into cyl #1 in the future. If you don't wanna skim the block, you could try to fill it in with something if it really bothers you.
If it were me though, I would just run it. Doesn't seem like you had any actual leakage into cylinder, so that's good at least. You definitely got it clean enough.
Did you check the block mating surface with a straight edge and feeler gauge to see if it was in spec? That would tell you if you needed to get it skimmed or not as well.
Also, as far as cleaning the pistons go, I've only done LS engines but I clean them every time. Not necessary, I'm just **** like that. Be careful about getting debris into water or oil passages in block, and I'd also recommend cleaning the head bolt holes out and using a thread chaser on them (don't use a tap, you specifically want a chaser).
