If I go with your supermarket route, should I stand them on a saucer of
water, or use some other method to get them started?

First rummage in the bottom of your vegetable rack to see if you have
got any that have already sprouted. If not, then leave them for a week
or two until they start to sprout. Then either plant whole or cut into
large lumps.
