Your GPA is really high. Will a higher GPA help? Maybe. But I think you will get more yield from your efforts if you directed your focus on a different area.
You could instead get involved in doing more extra curriculars. The time you would spend increasing your GPA .01 points could be put into completing some unique clinical, leadership or research experience. Working at a community health clinic or as an EMT would give you a level of patient interaction that most premeds lack. Or, working your way up to a executive level within student government will not only look great on the application, but it will put you in familiar terms with many faculty and administration on your campus. There would be plenty of personal growth factors making this a good experience, but a more direct benefit is the potential to get profs or campus deans/presidents to write really great LORs.
Alternatively, you could spend that time and energy taking courses at your school that provide other tangible benefits besides an increased GPA. These would include philosophy, logic, English and other humanities classes to refine your communication and argument skills. Ultimately, doing this would aid you in crafting your personal statement, scoring high on the VR section of the MCAT (if you haven't taken it already), interviewing, etc. Or you might see more long-term benefit by taking or retaking classes that provide a solid foundation for the things you will be learning in med school, like anatomy and physiology, biochem, immunology, etc.
The point is that your GPA is high enough to get your application considered based on the quantatative stats at any campus, so the success you have in other areas is what you will likely need to rely on to be a more competitive applicant.
