As for ripening, wrap individually in newspaper, store in a single layer, not touching, in a cool (but above 50 degrees) place, and check frequently. Wrapping them traps the ethylene gas they give off which speeds ripening. Warmer temperatures also speed ripening. So you have some control over how fast they ripen. Check here:
