August,
I'd second everyone who suggested getting a second opinion from a CCC (just to reassure yourself). My understanding is that today you can have your records and slides sent to a CCC and they'll tell you their opinion remotely.
I'm also in Texas and we got treatment at MD Anderson - if you need to know anything about care there, I'll be glad to share our experiences.
I can understand your apprehension. My husband wasn't given chemo - just radiation, and reading the stories here made me wonder why. I asked our surgical oncologist at MDA to explain the decision and she reasurred me by sharing the studies that supported the tumor board's decision to use radiation alone.
