Great advice everyone, solid stuff.
I do not think I will purchase one of these battery packs as my charger already fulfills this purpose, it outputs USB power. I am bringing 12x AA because each charger hold 4, and I will 4 in backup. The cost of a dynamo charger is also very similar to the packs you linked me to, so if I feel I need more I will probably get one of those.
Things I forgot to add to the list: tire boot, 3x spare tube each (different sized tires), patch kit, and a few KMC master links, super glue for tire repair
The luggage locks are
extremely small. I do not see a reason not to bring them. I know if someone wants in they can always cut the tent, but it's a deterrent. Someone can steal my car using a coat hanger or breaking the window, but I still lock it. Makes a would be criminal make that mental leap.
For rough weather clothing... not sure what to bring here. I've lived in FL almost my entire life and whenever it rains... well... I just get wet. We will be wearing full spandex kits so rain won't be an issue. The only thing I'm worried about is shoes.
As for spare cables, well, I already own a bunch and they take up little space and provide me with piece of mind. I think I will end up replacing the cables on the Schwinn, they are just over a year old now.
Yes, I will replace the rear rack

I just need to order the rear one. I was putting off ordering it until I knew for sure I didn't need that front rack. Wayne @ thetouringstore price up all the components; if I get the front rack & panniers with the rear rack and panniers I'm only saving about $30 on the bulk deal, so I can always call and order later for little opportunity cost.
