Since you've gotten your foot in the door, and presumably have some contacts there now, find out when the Drill weekends are. Attend as many as you can (well, at least the socializing/beer drinking aspects of them). Though, it wouldn't hurt to call and ask when the best times to hang out would be. You may even be invited to attend some of their training briefings. There are usually a lot of the part-timers around then as well, so you will have the chance to meet much of the squadron.

Also realize the enlisted folks there who are pursuing pilot slots have a leg up on you, so it's important for the unit to get to know you before you just show up for an interview.

Show interest and enthusiasm, but don't be annoying. I'd say 1 or 2 days/month over drill weekend would fit the bill...
