I personally LOVE Michelin X-Ice tires in the winter...had them on a similar sized vehicle and they're amazing! Other people swear by the Blizzak's, and I don't think you can go wrong either way. My dad made the mistake of getting the Canadian Tire ones, 'cause "they looked the same!". When the temperature dropped, they firmed right up and were pretty useless for him.
My vote for the Jetta: X-ice!
I put four 205-55-16's on for $700 taxes in, no rims. I don't THINK the tires on your Jetta are as low profile as that, so you might be able to do a bit cheaper.
Good luck
