You can strengthen your chances for acceptance by getting an above average GMAT score (600+), earning A's in other accounting courses, and providing a good explanation of your low GPA. Additionally, the rest of your application will need to be very strong to balance out your GPA.

I also have two years of work experience. I've worked at Standard and Poor's in a clerical position for a year. Would that help me out? Also would taking courses in an Accounting at a community college help me?

Your work experience would probably help, though I am not sure how much leadership you have gained through your professional work. Maybe there are other areas in which you have exhibited leadership: extracurricular, volunteering, etc.

Accounting classes would show your commitment to the career track that you desire. However, it seems to me that you would be more interested in a masters in accounting rather than an MBA. Why did you choose an MBA, in particular? If you want to work in accounting, it is better to get an MSA or MAC rather than an MBA, because you would gain a far more technical knowledge.
