MD How am I doing so far?

Hi! I was wondering if you guys can give me some advice on my stats. Im a 3rd year right now.

3.61 cGPA 3.54 sGPA
1 year of research on protein structure analysis so far: total ~250 hours of research
Volunteering at a local free clinic: On and off during summer and winter breaks ~52 hours
Club Communications Officer: 2 quarters so far
Mentor to a College Freshman (school program): 1 quarter so far
Shadowing: 2 hours...
Intramural basketball for 2 quarters
Recreational Martial Arts: brazilian jiu jitsu for a quarter but going to take more classes.
Tutoring high school students: going to start next quarter

I love tutoring/mentoring students and I have a great interest in doing rural medicine. I know that my clinical/non clinical hours are lacking but am looking for clincal volunteering near my school right now. About my GPA, I prioritized research over my classes so it took a toll on my grades my sophmore year. I went down from a 3.74 to 3.6.However, I managed to set it right and have pulled my GPA a bit.

So the questions is should I apply next cycle 2013 or should I wait until after my senior year, in order to improve my stats. I'm taking my MCAT April 2013 and I am aiming for a 34+.
