I tend to put 3-5 corms in 4-5 inch pots and then later plant them out as if one plant without separating the plants. This seem to do well.
If you get a cold frame make it a big one as once you have one you will also have an excuse to fill it up. A cold frame is useful for putting plants in that need a little protection but not special care. The protection could be from frost or from getting too wet. It's a half way house between greenhouse and outside. Loads available to buy or you could build your own. Go on go shopping you know you want to!
