Exactly what you're doing. To baseline be competitive for fighters you need a college degree, a PPL, and good test scores (>90, can vary a bit if you are strong elsewhere).
So, my focus areas if I were you would be:
1) do a good job in AFE (if you suck, you'll never get hired)
2) get a college degree with a > 3.0, get your PPL, and take the tests
3) talk to pilots when they're not busy trying to step to the jet ("hey sir/ma'am, how was the flight? - at least until they stop telling you to say sir/ma'am which they should do immediately), go up after drill and after you've done your work to talk to folks, etc.
