I just put the cooked pasta into freezer bags. When I want to use it I take it, frozen, and drop the pasta into boiling water. It has worked for me. Try it with one bag, and see how you like it....
Another thing I do with cooked SPAGHETTI which doesn't involve freezing is to make lo mein. There's a good recipe in Joy of Cooking for lo mein.
Good luck!
