With a 730 and very good work experience there is no reason why you could not reasonably apply anywhere, even Harvard. Since you have a year or two I would suggest working your butt off to try and move fast up that ladder, and seek out as much as humanly possible to LEAD others, even in small seeming things like organizing company barbeques or money collecting efforts for charities, etc. And make sure you have at least one community service position (again ideally one with leadership) over these years.
Additionally, as an African American you know you are eligible to apply through the consortium?http://www.cgsm.org/
Finally given your goals, I would also look at Sloan and Austin (for energy), and maybe Wharton too if you like the program.
