Profile assessment

Well, you certainly have a clear sense of your strengths and weaknesses -- I'm impressed! Top MBA programs will be attracted to those numbers and your strong professional experience. However, you're right to guess that this may be a problem for you as well. For European schools, I don't worry so much about community service, although given your age you will need to address the issue of "fit": how will you fit in with a somewhat younger crowd, especially in a highly social school like INSEAD? What can we learn about your personality through your application that will help b-schools envision you as a member of the group?
Most important for you, I think, will be clear goals: why do you need a full-time MBA at this point in your career? You'll want to show that you know clearly what you're doing this for, and precisely what each school you're considering might offer you.
You might also consider one-year US programs such as the Columbia J-Term; they often accept a broader age group, and your GMAT and GPA will bowl them over.But I would place emphasis on defining your goals and making sure you can explain coherently and convincingly why a full-time MBA is right for you at this stage in your career.

Good luck!
