@zeus1 - you are in the right place, and are asking good questions. The good news is that as a sophomore in high school, you have time to make changes today (if needed) to better your chances of successfully receiving both a nomination and an appointment to the Service Academy you seek.
@MidCakePa is spot on - "we don't know" and there are many variables in the game of Service Academy admissions.
Based on what you have shared, here would be my feedback:
Positives -
1) You are demonstrating leadership potential through your current role in the club.
-Is there a path for you to continue in this organization and rise to a position to where you are in charge of the club? (Club President?)
-Is there a project you can embark on in this role that would be remarkable and provide you with first hand leadership experiences to leverage in your admissions essays/interviews?
2) You are participating in organized sports
-Is there a path for you to make Varsity in wrestling?
-What are the "Letter" criteria for you as a varsity wrestler?
-Is there a path for you to take on a Team Captain leadership role within the team?
-Is there a need for you to be a two-sport athlete? Do you have aptitude to be successful in track? Doing two sports simply for resume building may not be the best use of your most valuable resource -- time.
3) You actively volunteer in your community.
-This is great. Don't stop.
-Are there opportunities for you to lead these service projects and add to your demonstrated leadership experiences?
-There is no set limit as to how much service is enough -- the US Air Force believes in service as a top priority - we consider it a core value: "Service before Self"
Negatives -
1) Your weighted GPA is fairly low when compared to those who have gone before you and been successful in receiving an appointment.
-If we assume the grades are done for this semester and factored into your GPA, you have 3-4 semesters left that will impact the GPA and be considered by the admissions board. You have time to raise this number.
-If we assume things do not change much, you have an opportunity to demonstrate academic aptitude in your standardized test - SAT/ACT. You would need to crush it - but you know that, and it is why you are likely working on prep for those TODAY.
