1. Strong, as long as you add some more middle tier schools. Looking at your school list, it's surprising that you were only able to get one interview, but I'd add quite a few more middle tier schools to boost your chances.
2. You have a good and very well rounded application, so there's many things you could do. You could do academic/clinical research, and really aim to get publications, as those serve as pretty meaningful updates during your application cycle. If that doesn't interest you, you could lean more towards the service side, and continue your work teaching in underserved areas. Finally, you could try to find a job as an EMT.
3. I don't think these things necessarily hurt you, and I doubt including/excluding these would make or break your chances of receiving an interview even if they did.
4. Honestly, I have no idea. It probably can, but I can't say for certain.
