Probably about 3 weeks to being ready to plant; I usually allow them a month -- as long as they're out in the light the sprouts stay short so there's plenty of leeway with the timing.
Also, if you're using larger potatoes and need to cut them up into pieces to plant, do so several days before planting so the cut edges can dry up a bit, which helps to prevent rotting (I believe some people dust them with sulfur after cutting, although I've never done that). The chunks should be roughly the size of a golf ball, with at least 2 "eyes" on each one.
