Clearly I do not want to suggest anything that your doctors are not recommending. Given your very early staging you have that on your side, few of us get a T1N0 find here. Having said that, I am also not a huge Erbitux fan although I like that they have explored a less damaging treatment modality as an adjunct to radiation therapy. Given a ten year history of precancerous lesions, I would personally choose to tough out what has been the standard of care - rads with cisplatin (or carboplatin if you don't tolerate cisplatin well). This gives you a scorched earth policy, that has the highest opportunity to eradicate what might be the opportunity for "field cancerization" to be taking place. Had you not had so many years of precancerous lesions, I might think differently.

Please note. I am not a doctor, I do not know everything about your personal situation, and I may be basing this opinion on a lack of knowledge, experience, and more. But I think it is worth asking your doctors about, and then after hearing their opinions, making an informed decision about which way you should go. Erbitux has some unknowns associated with it, and disagreements within the medical community about when it should be the drug of choice and when not. Cisplatin is a completely known commodity having been used for a very long time.
