Am I being totally unrealistic? (Qs,Profile Evaluation)

Hello everyone,

I took my GMATs this last August and was pretty happy with my score. I got a 700 (47Q, 39V, 6AWA), which is 90%. I was under the impression that once a 7something score is reached, GMAT is emphasized less. However, I've been talking to people and have been getting vibes that it's not that good of a score for the schools that I want to go to. I wanted the GMAT to be merely a foot in the door--not THE deciding factor. Am I being unrealistic in my school choices? See the list after my profile evaluation.

This is my profile:

Age: 23
Nationality: Indian American
Sex: Female
GMAT: 700 (47Q, 39V, 6AWA)
GPA: 3.868/4.0 (Summa Cum Laude) from a top 10 US Public School.
Looking to enroll: Fall 2011

Work Experience (currently): 2.5 years in the biotechnology sector.
Key Work Accomplishments:
-Startup company so heavy involvement in setting up the company including working closely with the CEO.
-Managing a project in the Diabetes field, controlling all sectors involved including conceiving the idea, targeted marketing, and implementation.
-Designing and managing a structured Customer Support System.
MBA focus/interest: -Consulting (Healthcare) with a big firm initially and then for a Social Business in the long run.

Extracurricular:
-While simultaneously working full-time, I have also been co-managing an India-targeted non-profit organization. I helped found the environmental awareness program at this organization and have been on the executive board for the last 2 years. I was instrumental in making the organization last beyond it's first year. Running this organization has developed skills spanning all aspects of business management.
-I have also recently started working with a Harvard Graduate Student group to provide a holistic, voluntary consulting services to young individuals working for grassroots international development projects happening in India. My specific project is essentially a team of 2, communicating with a field partner in South India.

MBA Schools of interest:
-HBS
-Sloan
-Kellogg
-Chicago
-Stanford
-Columbia
-Stern
-Fuqua
-London Business School
-INSEAD

Questions:
-Am I unrealistic?
-Are there any other schools that I should consider? Should absolutely eliminate from my list?
-I plan to do a trial application run for Fall 2010 and apply to 2-3 best/semi-best schools. Good idea?

Thank you so much for all your help! So sorry for the uber long post!

Cheers.
