I really think you need to improve your GRE score to be reasonably considered for admission. Your quant is great, but verbal and writing need to be higher. I had the same problem, was denied admission the first time, studied and retook the GRE (did much better on weak areas of test as well as improved my application in other ways), and gained acceptance the second year I applied. I agree you should apply to all the schools, to improve your chances.
