I don't have strong feelings about cranks. I like the look of older Sakaes and Suginos, but Stronglight's fine too. Really, anything that'll match up with a bottom bracket you can get. If you really intend to hammer the thing, we might have to rethink this a little.

DiaCompe sidepulls. They work in the summer, in the winter, in the sun, in the rain (I actually preferred them to the Campy Record brakes I replaced them with). 500's would probably work. I have some Shimano 600's floating around, but haven't ever used them.

But Suntour derailleurs for sure. I kind of liked Cyclones, but I don't recall how many teeth they can wrap, so maybe something with a little more cage if you're running a triple. Front derailleur doesn't matter. Heck, leave it off and go as a five speed :-)

Suntour Power Ratchet shifters. Functional.

Hubs... I've not had a truly bad experience with a hub, and actually kind of like the Sanshin/Sunshine as others have said.

And wear sunscreen.
