Sundown -- you're definitely not a "lock" for all of the top schools (very few people are), but based on your stats alone, assuming the rest of your application is solid, you should be in a position to get a few interviews at some of the "top" schools. You might be surprised though -- some of the "lower-ranked" schools may impress you more than you imagine.
It sounds like you're in a good position. It may be hard to hear this, but you've done what you can, so at a certain point you just have to relax and see what happens -- much of it is out of your hands at this point (except for the remaining secondary essays and the interview preparation).
