Of those applying through AMCAS in the last three years with your stats, 32.9% received an acceptance, including those with significant modifying factors on their application which may not apply to you. The masters GPA doesn't get figured into your application GPA, but it is a nice experience to list. If you can get your MCAT up to a 34, your chances would increase to 55.1%. I've never seen data as to one's chances of getting an interview, so I can't answer that.
Your chances of acceptance if you apply through the DO school application service would be very good.
