How do you get your APR bullets together and what type of things should you put on there to help in promotions?

I have just finished my first full year in the Air Force. I am a Traditional Resetvist working the typical one weekend a month, two weeks a year. So once my promotion to E-4 comes around next year, I know testing for E-5 will come in the next few years. When it comes to it, how do you get your APR bullets together and what type of things should you put on there?
