I'd leave the one in factory packaging as is, just in case you change your mind and want to sell it. Otherwise, waxing is fine. It's also good to keep them out of direct light (the bag would be good for that).
I doubt I'll be selling it, short of breaking both my legs and not being able to ride ever again.
@Sedition: One of the reasons I'm putting it away right now is that having it out makes me realize it'll be another 7 and a half months until I can ride again....
