I has Erbitux and had a good result from it. I do remind posters that chemo only assists radiation. It is the radiation that kills the cancer and carries the load. Chemo can give you better odds of getting the cancer but it is only a 5-10% additional help so I say concentrate on the radiation and or surgery.

Given the fact that you had two nodes show positive for cancer I would also get the Neck Disection. If you had no signs of cancer in the nodes I would think it would be something you would give some thought to but having found cancer in the nodes I would not risk it.
