I used a 6f for three Winters - I did use the car for a few days when we were on strike in January 2010 and the pre-dawn temperature hit -15 in Crewe - and had no problems. If you use a cover make sure that it's breathable and don't cover a wet bike. Sitting uncovered does it no harm while you're at work, but carry something to dry off a wet seat.
I had no problems with brakes sticking or any of the common Winter issues. The one thing to watch, and I'm not sure if it's the same on the '12 bikes, is the chain adjuster at the end of the swinging arm. Make sure that the drain holes are kept clear and water doesn't lie inside the swinging arm.
I'd suggest Phillips eXtreme Vision or Halford's Superbright bulbs in the headligts.
If your commute is short - less than about 5 miles - think about an alternative to the bike. Anything less than about ten miles could give long term issues.
Use a tap water hose at least once a week to rinse off any road salt. That will cause corrosion if left. So will keeping the bike in an unventilated garage or a garage that's heated to more than a few degrees above the dew point unless it's cleaned and dried first.
And be aware that riding on a freshly gritted road is almost as bad as riding on ice.
