Hi,
I am a 100% anthropologist- however I have scores of friends who come from other departments- Pol Sci, History... who got places in top Anthropology programs. Methodology is not important at all in your statement- Anthropology is mainly qualitative, but it is also such a syncretic discipline, and you will have to take research methods courses like anyone else- they don't expect you to have read research manuals!
What really matters, in such a competitive sector where 5 people are selected out of a 100 or 200, is your fit with the department and the people you want to work with. This has to be quite specific. Be very specific on your research interest- and make it sound concrete and intertwined with some part of your personal/ academic history.
I don't have stellar grades or GRE- I got accepted with very good financial offers in both top and average schools where I had some meaningful contact with professors, and got rejected in top and average schools where, honestly, there was little I could do for my research project and interest and I would have been unhappy.
So the trick is: passion, a story to tell, an idea you want to explore, and some indications that you have already started to explore it. Good news is, you don't have to force yourself/lie/freak out about not having the best grades in the country (yours are high enough to pass the lawn-mowing selection)- just bring up your passion and, as other have suggested, contact people. Early on! September is a good month to start.
Good luck!
