You do have a pretty well rounded application which would get a good look. Outside of what Shadow said about writing solid essays, you should also look at which schools have essays topics that fit you AND diversify your schools for some schools where you have a higher chance of acceptance if you're deadset on attending 2010.
Schools such has Haas and Tuck have a low acceptance rate because of the small class, so you can probably hedge your risk there by applying to only 1, same with Wharton,CBS,Booth Probably pick 2 of those.
Ross is your best bet right now but it still has a fairly low acceptance rate so you can probably concider schools like TEPPER, Texas, UNC as backups.
Unfortunately you are international which makes it a little bit more difficult applicant pool and if you want close to a guarentee, you will need to aim slightly lower schools.
