Also, if you can, get the Brammo windshield...it could extend your riding season...takes the wind off you chest...
Of course good winter gloves are the most important item for winter riding...that an a fair bit of insanity... (luckily I have that in spades)

+1 on the windshield and gloves.
And at my age (greater than the speed limit) I've become a weenie for riding in the cold (below 50F) without heated grips and a heated jacket liner, the "magic layer."
If you're looking at riding in New Mexico high desert with the winter approaching, I highly recommend electric heat.
There's nothing quite like ADDING heat into your body, rather than meerly trying to preserve your own meager output. In all my years of riding I never, ever thought I'd ride in the winter and actually be too warm, having to turn down the controller a bit. Wonderful!
