Re: How bad do my pistons look?

Clean up the areas you marked and the matching areas inside the head. Clean the tops of the pistons too, of course, but be careful of stray wires from the wire brush. I've seen engines where a strand had stuck under a valve and caused it to burn to the point that it had to be replaced. Maybe use a shop-vac while brushing/scraping to minimize any wires or bits of carbon from getting stuck anywhere and clean and vacuum thoroughly again before cranking the next piston up to the top.
