You can cancel it at any time, but you won't get your money back. Your best bet is to practice on a game type you tolerate the most and get used to the game play. Halo 3 will be similar. That would give you practice and you wouldn't be wasting your money, since you will be using your account. There are other things you can do on the marketplace, too, if that is interesting.
Personally, I'd keep the account and play Team SWAT, Slayer, Snipers, whatever to get practice in. If it is only a 3 month account, then don't renew it. If it is a year, keep it so it is active when Halo 3 is out...
