Update:
Have found the USB chip on Digikey. Cost ~£2 :)

Would an acceptable Crystal be http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=X433-ND (http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=X433-ND) ?

also called the ECS-160-S-4

Thanks

All of those questions you can answer by simply reading the ATmega640 datasheet, glancing at the Axon II manual, and a google search. ;)

The resister array is 180 ohms.

That crystal isn't SMD, but it'll work. Just follow this tutorial to select capacitors:
