Throw in a set of Gerbing sole heaters that go inside your boots and you can ride down into the teens F and below; my wife and I were out in 11F temps. one night and while not toasty warm, we were reasonably comfortable.
Well, until the main fuse popped, the bike quit and we were standing on the side of the road... then it got kinda' cold. :-)
Sounds like you are gearing up very well for enjoyable riding! Good luck with that when it cools down but again, sounds like you have it covered.

But....I couldn't pass this one up....
