Congratulations, Doohickie.
I was going to say something snobbish (sorry, but I laugh at those temperatures now, laugh I say ;-), but then I realized how big of an accomplishment it was for me to ride my bike past September not to long ago.
Just keep learning as you go along and pickup whatever additional clothing you need. I just picked up a watchman's cap, an ear warmer headband, and some gloves for $2 from my local salvation army.
