Agree with the general comments mentioned. You've put yourself in a good position with scores, and at least have some research. I have a few suggestions, perhaps a bit different than what you have heard.
Coming from a medical school without an orthopaedics program, several questions are going to be raised. How did you come to love orthopaedics? How do you know you like it, or fit in? How much do you really know about orthopaedics, or orthopaedics residency? Did you only start learning about it, for real, when you started away rotations just a few months ago? I would ask you these questions, so think you should anticipate them, and work to eliminate even the idea that you don't really know what you are getting yourself into.
I've posted elsewhere about this, but think you in particular need to be knowledgeable about the history of the field - there are a few books, one I like that is a cheap ebook I mentioned in the section on 'what books to read' but there are a few out there. If you get asked what orthopaedics means or how the field got started and you don't have a clue, especially from your position, it'll look bad.
Assuming the local surgeons you've been working with are orthopaedists, or at least some of them are, I'd ask where they did their training. If they trained at places you might be interested with, and if they still have a connection to the program, that could be a HUGE advantage for you. A person could vouch for you, you do an away there and crush it - you'd be set. I've seen this work for people before, in not dissimilar situations.
In your position I'd say do at least 3 away rotations, ideally at places you've researched enough to know you'd really like to go. Don't expect to get a ton of interviews outside your geographic area except at places you rotated. And most importantly, be super prepared to absolutely crush your away rotations - there are several posts out there on this.
