From what ADCOMs have told me, they accept people early decision if they feel that they would eventually accept the person anyways. Your scores are definitely competitive, so if this is your dream school I'd say go for it!
Pros
1. Your chances are better if you are above their average GPA and MCAT scores because they won't know what the rest of the applicant pool is like (which is getting more competitive each year).
2. You'll know far ahead of time if and where you'll be going to medical school. This means less stress, and will probably add a year to your lifespan.*
3. You'll save tons of $$$
Cons
1. You'll be restricted to that one medical school during the regular application process time-frame, and if they end up not accepting you you'll be a little tardy in getting applications to other schools. Make sure you are prepared to apply to other schools just in case.
Only apply early decision if you are a good fit for the school, your GPA and MCAT are competitive, your ECs fit in with the school's mission, and this is truly where you want to goto school.
*Note: the application process on the surface doesn't look all that bad, but it takes a significant toll on you over the 9+ months. It can be very tiring and stressful, to say the least.
