Sweet project. I bet the paint is going to look lush once cleaned and buffed. As for the brakes, here's some advice that might save you some headaches. Before you buy any v-brakes, measure the distance between the canti studs. Bikes from that era often have narrower spacing which can be incompatible with v-brakes. Also, if you're using v-brakes, some brake boosters would help stabilise the system since the fork blades aren't exactly beefy. If the stud spacing is too narrow, and you go down the canti route, I'd recommend low-profile shimano ones like the br m650 for example. Set up properly with kool stop eagle pads, they work pretty well. A fork mounted cable hanger might also help with brake judder. With cantis, a proper set-up is really important since you have to make the best of the limited mechanical advantage of the brakes. That means that there should also be as little friction as possible. One good way to decrease cable friction (especially for the rear brake and even more so for a tandem) is to put some slick lube liners around the edges of cable stops. You can simply cut off a 2cm piece, heat it up with a lighter and form a stop on one end of them. This may all sounds like a lot of hassle - which it is - but the marginal gains really add up with cantis.
