I agree with tsl and from the looks of your gear set up you'll be totally fine, with one caveat. I would wear a thin skull cap alone, or maybe a thin balaclava. Exposed facial skin in that temp isn't a big deal at all for me but I'm really acclimatized to it. I'd also be willing to bet that your feet might get sorta cold by about 3/4 of the way in regular cycling shoes, but so what, it wont be the end of the world or your toes.
The folks here that are sounding the alarms and telling you not to ride are the ones who don't ride in cold weather and probably never will. If you are determined to do it then just go for it. It's not rocket science. Get dressed, get on the bike and ride.
