Electric, electric, electric... and as was said, be windproof or get behind a substantial windshild and lowers or a fairing... wind will leech your body heat faster than you can make it at those temps, for anything longer than a 20 min ride...
I commute around 75-80 miles one-way down to the high-twenties, but use a Gerbing heated jacket liner... [rotect head and upper body, a balacava or neck-gaiter will help -- I use a gaiter because I must go through a guard gate and they must see my face... otherwise I wear about what your wearing except for the elctric and I wear leather on the outside... oh, and snowmobile gloves for temps below 35 or so...
