If you want to go to grad school, just be sure to have everything else together. Spend a decent amount of time getting ready for the GRE and get a solid score. Make sure you have some good references. Put a lot of time into your personal statement.
If you don't have a few profs who know you well enough to give you a solid recommendation letter, start working on that now.
I found the grad school application process to be much less of a numbers game than undergrad. They want to see a GPA and GRE that demonstrate that you will be able to handle the grad program, but mostly they want to see that you have a solid idea of what you want to do and why you want to do it at the specific school.
Of course, this all depends on the specific field you are going into and the specific school, and even the specific person in the department who happens to review your application.
