Your GPA is just fine. 3.7 was the median for matriculating students last cycle.
Now your questions–
Graduating early won’t hurt your application, but you will be compared (in terms of ECs, LORs, achievements, honors etc) against students who have spent the full 8 semesters in college.
For what purpose? If med school is your goal, having a Masters won’t help you at all. Grad degrees and grad GPAs are not considered when making admission decisions.
Frankly it would be more useful if you took your gap year and did something meaningful (and, if possible, healthcare-related) with it–work as medical scribe, work with the health corp at Americorp, do TFA in a underserved area, work or volunteer in a public service/public health job, etc.
Majors are largely irrelevant for med school admission; adcomms only care if you have fulfilled the admission requirements. If you’re happy with your major–it’s fine.
Only if you actually work or volunteer as an EMT; otherwise just taking the class is meaningless.
If you are thinking of looking for an EMT-B job, be aware that in many locations, there is an oversupply of EMT-Bs. Please check your local job market before pursuing EMT training. Part-time EMT-B jobs are hard to find.
Long term community service, particularly with at-risk populations. (Elderly adults, hospice patients, mentally ill, non-English speakers/recent immigrants, impoverished/disadvantaged, LGBT, etc) Adcomms value community service above research. Leadership is another area you can work on.

Studying before you have completed all your pre-reqs is a giant waste of your time. Make sure you’ve taken stats or biostats before the MCAT. If you have the option of taking genetics as one your major electives–take it.
