Water pump would be a good idea. You need the head gasket, intake gasket, exhaust gasket and camshaft tower gasket. I would also recommend ordering the camshaft seal (there is a Teflon or onion skin seal here too) and doing that while you are at it. More than likely you are going to need a replacement camshaft bolt, they strip very easily.
Additionally, removing the belts is a good opportunity to do the front main seal, the balance belt seals and the oil pump sleeve also.
I would also consider replacing the fuel supply and return lines, and the fuel rail to damper line too. You will be disturbing those and they run directly over the exhaust header.
...hey, you asked!
