It's always nice to start looking into it early.
Here are a few questions that you may want to consider:
Have you taken any stat/econometrics courses or do you plan on taking them? What about micro/macroeconomics?
Before coming up with a list of schools to apply, I would strongly suggest that you figure which area of research you want to pursue (financial, managerial, tax, audit / archival, analytical...) Once you want an idea of what you're interested in (and your GMAT score), it will be much easier to come up with the list.
