MBA to IB

I am currently working at a fund administrator for PE/VC/HF as an investor services associate. I now realize I want to break into IB. I know any chance will be through an MBA program and aiming for a M7 one. I had a 3.4 GPA and went to non-target, was the captain of the mens lacrosse team (only extracurricular). I know that I should shoot for a 720 on the GMAT. I am also planning on volunteering now. But was wondering if there is anything else I could do to improve my chance of getting into these programs and to stick out. I also wonder if a CFA would help me get into MBA. I hear so much pros and cons for the CFA related to MBA and IB. Thanks!
