MD Chances for MD/PHD? Possible Advice?

Howdy all!

This is my first post, so please forgive me if I make any mistakes in formatting or nomenclature.

Anyway, I have an sGPA of 3.47 and a cGPA of 3.56 with a projected MCAT score of 35. Due to my current study habits, at least an hour of studying a day with the tests over a year out, I am inclined to project fairly high. There are reasons for the low GPA, and only one year of noticeably bad grades.

As for EC, by the time I apply to some MD/PHD programs, I will have conducted a research project for one year in a local lab. The research will be published. This will also be my honor's research thesis. Furthermore, as part of the honor's society, I have also conducted over 100+ hours of varying community service.

Also, I don't know if this will be considered or not, but I intend to spend a year in South Korea teaching English as a post-graduation break.

One question I have is whether or not I should spend more time in research or not. If so, would pursuing an MS be wise?

Any information would be very helpful. Thanks.
