Thanks for your post. You have a solid basis to your application, namely a strong GMAT & GPA, showing you can handle the academic side of b-school, and some solid work experience and activities/involvements. I would say nothing so far will keep you OUT of the top schools you have mentioned; in terms of definitely getting you IN, it often comes down to how you stack up against other well-qualified applicants. I would encourage you to think hard about what you think makes you, YOU... makes you unique; about how you would like to be remembered after someone reads your application. About what you think you would bring to the class. And to put a lot of thought and effort into your essays, as you can make a strong impact on the readers through the essays if done well. You could add a school or 2 outside the top 8 or so, if you'd like to increase your odds overall, but certainly only programs you'd actually consider attending.
