What shifters do I need?

Those should work for the shifters, and they're fairly nice levers. But what kind of brakes do you have? Those levers are meant to work with cantilever or caliper brakes, not linear pull (V-brakes) or disk brakes. If you have V-brakes, you'll need long-pull brake levers.

I have traditional cantilevers, so those should work. Great, thanks!
