The 720 is easy. I'd build it with suntour vgt rd and bar cons. For the crank I'd run a 110/74 bcd crank like an early sugino or shimano. For the cantis, I'd hunt down the shimano br m732 cantilevers as they work great and will allow you to run 700c wheels. For wheels, something built up with superchampion 58 rims would be my first choice but the sun cr 18s are a solid choice as well if you want new. For hubs, specialized sealed or phil wood would be my first choice.
The campy stuff would be sweet on the 957.
