Tubes are made from butyl rubber, a synthetic rubber, which has a good shelf life and is fairly resistant to ozone attack. I wouldn't bother with airtight containers unless you're talking really long term, but it couldn't hurt. The most important things you can do is keep them away from direct sunlight and oils, and protect them from sharp objects in your tool pouch, where vibrations can damage them. Biketube Brand's TubeSock is perfect for this application (shameless self promotion there!).
Is coating the spare tube in powder so it doesn't rub on itself a good idea or bad idea?

Obviously it will prevent friction wearing...but will the powder dry it out prematurely?
