Procrastinator -- for what it's worth, I had a lower EFC last year (~$11,000), I'm an independent student, and I'm receiving absolutely no financial assistance from my family. However, my dad technically has a good income, (whose info. I submitted to the school directly), has a good income, although he is close to retirement age, like you parents. I did not qualify for any need-based grants or loans -- just the standard package of Stafford loans.
Apparently, they do take the age of your parents into account -- if they are close to retirement age, it's considered less likely that they will be able to contribute to your education. However, with two parents who work and an EFC that high, I'm guessing you won't qualify for any need-based grants this year. But, each school is different, and you can always try to plead your case with them. Good luck.
