sounds like you've got it well in hand.
i'd do a dingle ball hone and some budget friendly rings. the bearings looks pretty darn good, but you'd have to make a judgement call there because that's something that can't really be ascertained via pics-- unless they're bad, that is.
checking the pump and and reusing if it's in spec is a good move, but a new pump is cheap insurance. the same goes for the harmonic balancer.
because it's open i'd do a reground or a cheapie white box cam. even with a stocker 2bbl.
i know the thin felpro gaskets are a bit of coin, but in the every little bit helps department that might be money well spent.
i'd pop for a low key 4bbl set up if the budget allows.
