I wouldn't be too concerned about your GPA as there isn't much you can do to improve it. Like other users have said, just explain in your personal statement why your GPA is on the low end. You very well might need to retake the GRE, but that's not a huge deal. When you complete applications, you won't need to report all past GRE scores. Your letters of recommendation and professional experience (research, counseling, volunteer, etc.) will carry more weight in the selection process than GPA. Your letters of recommendation should come from whoever you think will provide the most personal, thorough account of who you are, your accomplishments, and why you are an outstanding candidate for xyz program.
My undergrad GPA was a 3.25, but I've received four interview invites to BNS or Neuro. PhD programs thanks to solid GRE scores, strong letters of recommendation, and several years of technician/clinical experience. So it can be done!
