I think as far as GPA and observation hours go, you're in a solid place. Just make sure that you have some variety in where you observe (multiple clinics, specialties, etc.) and really highlight any volunteering or leadership opportunities that you've been a part of- I feel like a lot of programs want to see some variety and involvement in areas outside of PT.
I can't say for certain you'll get into every school you apply to, just given the fact that each program looks for different things in their applicants! Some schools place the most emphasis on GPA/GRE, whereas others look more at essays and leadership. To give you some perspective, I got waitlisted/denied from programs that I was certain I'd get accepted to, and I got accepted to programs that I didn't think I had much of a chance with. Your GPA and hours look good- but remember that essays, letters of recommendation, and leadership/volunteering also carry a ton of weight so be sure to focus on those when the time comes for you to apply. Good luck!
