Welcome!
Pretty bike! I'm new here too. I had some wrist pain on my first real ride and when I asked about it here I received this advice "Numb wrists might be from handlebar height relative to saddle height, and/or the type of handlebar. I think there are threads discussing these, and talk to your bike shop." Also it was mentioned that a tense grip could cause it. I'm sure they'd recommend a bike fitting.
You can search for info on bike fit, I think that should pull up a bunch of info.
Edited to add, I found this about back and neck pain: http://forums.teamestrogen.com/showt...ndlebar+height
