I really think you have a shot at getting a merit scholarship. You have great grades, EC's, and if you have a kick ass essay then I think you'll be all set.
I started a thread not to long ago so you can check it out for some information on colleges that are need-blind and full-need and also on scholarships.

I know somebody else asked, but what state are you in? and what states are you looking to go to college to?
-best of luck.
