Will this work? Or does the board have to be USB-powered while uploading software?

Yes - I have been doing this successfully, since I've been playing with the code. I left the jumper on car power and updated using a laptop (running on battery power).
I guess the arduino is powered so doesn't care how...
For info I have a freeduino, usb version.
