Generators and flashlights are good if you lose power. Just make sure you have fuel for the generator, and it's in good working order. Otherwise...I'd say just make sure you've got enough food to last a 2-4 days, and some bottles or jugs of water on the off chance your pipes freeze. And of course a good supply of video games, movies, and books are a must.

If you have to go out at all, make sure you have a snow shovel, some blankets, and some road salt (or sand, or even kitty litter--not to melt ice, but to provide traction if your car gets stuck) in the trunk of your car.
I'd say not to worry too much, but...I'm from Michigan. We call a foot of snow "Thursday" around here this time of year.

Really, though--chances are you'll be fine.
