I don't know about all of the items on your list, but when I had an engine rebuilt, there had been damage to the cylinder walls putting me on the path of looking for new pistons.
The bad news, you're probably looking at custom made oversized pistons as no such beasts exist on the open market. I've seen comments from others on the forum mentioning where they went to get some made when they decided to do this.
In my case it ended up being easier to re-sleeve the cylinders than hunting down someone to make pistons. Luckily the pistons themselves were in perfect shape so nothing else needed to be replaced. The damage was caused by a head gasket leak that rusted the piston rings to the cylinder walls.
Good luck!
