Several companies make new sleeves for Honda blocks, Darton would be my off-the-top-of-my-head choice, and normally you can see anything from ductile steel to chromoly listed in the cylinder materials list. I would go by the manufacturer's recommended use more than worrying about what they're made out of.
As far as what other materials can be changed out. You can change cranks, rods, basically anything that bolts into or on an engine can be changed if you really want to. Although sometimes there's no direct part to replace it, in which case you'd be looking at custom stuff [$$].
