Drive with caution, don't go 100mph everywhere you go, just because you have a 4wd.
Experience helps out more than tire setup, if you never driven in the snow, I would take every advantage you can get.
Studs help out alot when its icy, they help you stop (especially when you have to stop suddenly), and they help when the road curves.
Born and raised in Alaska and have been to over 30 countries. I have to say, besides the middle east, Alaska has some of the worst drivers I have ever seen. On top of all the alcohol related accidents there as well.
Take your time in the winter, never go immediately when the light turns green, somehow in the past few years a red light has become a suggestion and not a symbol to stop.
