I've driven in snow most of the past 20+ years, so I've seen it all.
Biggest two tips: Get good snow tires. Blizzaks are awesome, but soft so don't run them any longer then you have to. Tread-life on dry pavement is not long. Nokian Haakapalita's are great winter tires, but spendy as hell.
Tip two: Don't spin your tires. If you are losing traction in snow/ice, spinning tires just melts the snow/ice creating water, which then makes it even more slippery.
Oh yeah....one other easy thing to do to increase traction in 2-wheel drives: Throw two or three sandbags in the back over the rear axle. The extra weight gives you added traction.
Good luck!
