Front wheel drive or four wheel drive will help you avoid slipping more so than rear wheel drive. Also, whether or not you use long-johns depends upon the cold and how often you have to walk places. I used spandex under my jeans before in western mass and it was so awesomely warm. I did deal with it for three years without doing so, but since i spent so much time walking between class it was a welcome change to wear some leg protection - the buildings also tended to be cool even with the heat on.
Oh, and right before a storm, everyone runs to the stores to stockpile everything ("GOTTA GET THE BREAD AND THE MILK"). Fill up pots and/or bathtubs with water before a storm so you can flush the toilet, and if you have a gas stove you will be set regarding food. If not, get some snack foods beforehand but try not to go to the stores last minute since there will be NOTHING.
