Most important tip: if you buy a frozen turkey, move it from the freezer to the fridge at least 3 days in advance. Otherwise you'll be like my Dad, who calls me every SINGLE year to complain that a 10-lb turkey is taking 9 hours to cook because it was frozen that morning.
(and don't forget to check the turkey's cavities for giblets, the liver, the neck, etc. sometimes they're wrapped in plastic and you do NOT want to cook a turkey that has plastic in it.)
I also swear by frequent basting with a solution of 50% melted butter and 50% white wine.
