1. A 30 followed by a 29 likely wouldn't even put your foot in the door at top/competitive programs. However, this is only going off of an MCAT score without looking at your whole application. Still, with a 30-29, I wouldn't spend the money on apply to those places.
2 and 3. Not unless you can knock it out of the park. However, you'll be dealing with a test that not much is known about, so I wouldn't count on doing better.
In regards to your last 4 AAMC practice test scores, were those retakes? If so, that explains why the scores were higher than your actual score.
