You're probably too invested in the idea of going to b-school right after college, so it'll probably be pointless for anyone to tell you otherwise.
Anyhow, you're NOT getting into a top school unless you have a 700+ GMAT. Yes, you seem to be a talented kid (and yes, I emphasize "kid" even if you feel you are mature beyond your years) -- but the adcom will see you as a kid. You haven't graduated college yet, and no matter how amazing you think your experiences are, it's not the same as working full-time. And even if you get a 700+ GMAT, your chances are still slim.
Also, talking about your father or grandfather in your applications will only give the impression of a kid. And in any case, your father and grandfather's background has no relevance to your b-school application, because YOU are the applicant, not them.
I hate to be harsh, but don't be disappointed if you don't get in right away. In any case, you'll get a lot more out of it if you have a few years post-college.
My guess is that you're going to ignore this and apply anyways.
