Gino,
I agree with Brian about doing the radiation now. I was in a somewhat similar situatuion as you. My doctor told me my path report was negative after surgery and I needed no additional treatment. (They did not remove any nodes). The second opinion I sought in Boston produced a report that I had a positive margin in the surgical tumor bed and needed radiation. Which I then received.
Every one on this board who has received radiation will tell you that it is no walk in the park but it is tolerable, survivable and hopefully life-saving.
I would encourage you to ask your doctor about combining chemotherapy and radiation. There are new studies that seem to indicate better outcomes if the radiation is combined with chemotherapy or one of the new drugs like
Erbitux. See this story in the news section of the site:

Good luck with this difficult decision. - Sheldon
