Job hunt advice needed for first "real" job

Hello! In short, I went right from undergrad to grad school so that is why I am 25, married, and now just looking for my first real job. The job I'm looking for is a school psychologist position in a school district (or charter school, or ANYTHING really). As many of you know, it is really tough these days to get any job in education. I went on a handful of interviews over the summer and wasn't offered any of the positions. Some of the interviews were not so great, but there were some that I felt I nailed, so it was pretty disappointing when I didn't get it.

 It seems like to get a job in a school district these days, you really need to have connections. There is a part time posting for the school district that I live in. Even though it's part time, I know the full time psychologist there is older and would probably retire relatively soon. It's a really good district too, so I really want this job. I had met with the Pupil Services person and the full time psychologist about a year and a half ago because I was interested in doing my internship there. Our meeting went really well, but I ended up turning it down for a paid internship.

When I saw this posting, I emailed the pupil services person to see if he remembered me and expressed my interest in the position. He wrote back and said that he did remember me and told me when he plans to do interviews, and when the position would start. My question is, do you think there is anything else I can do to show my interest in this job? Would it be out of line to also email the psychologist to let him know I'm applying? Some of the interviews I went on had the district psychologists involved and others did not, so I don't know if he even has a say in who is hired.

 Thank you in advance for any advice you have (or any on interviewing too, for that matter!)
