I graduate in May, but I've held at least one job (up to three during one semester) throughout my college career.
I'm a comp sci major and all of the jobs I've had were related to that. Some IT and some programming. In either case, these jobs helped me in school because I got to put what I learned into real practice.
That being said, if you can find something in a field that is related to your major you will help your studies by practicing what you've been taught. I'm sure everybody will have something different to say, but as you've noted you don't want to get too far away from your books.
On a related note -- I've found it best to try and work for a smaller, more personal company. They will often be more willing to give you days off to study for tests and/or leave early on some days. I did work for UPS for a semester and my manager was very willing to let me go for whole days sometimes to study... It will help you apply for a job as an intern and let them know that you are a college student (remind them if necessary) and they will work with you.
In all cases, be very upfront about your schedule during the interview process and throughout. When you tell them your availability at the beginning you obviously want to be competitive, but you have to be realistic. If you are taking a full load of classes and will need at least 5 hrs a week to study, figure that in where you need it. Also (very important) if you have to drive some distance to work, make sure you figure that in as well. You don't want to miss a big test or assignment due date because you had to drive 45 mins from work.
In that same thread, I know many a college student who got jobs on campus so they were never too far away. And obviously these jobs realize you're a student and will work with you.
Sorry for being long winded. Hope that helps. I know money is a big issue for a lot of people out there, but you have to always have your priorities straight. You have to go to class and do well. One of my roommates is a work-a-holic and will be entering his 7th year (for his BS STILL) because he's done so poorly in classes. Especially if you're wanting to be in AF, keep your grades up. #1 priority.
If money is still an issue once you do get a job... Remember, you're in college. Learn to live like a poor person. My freshman year I literally ate PB&J sandwiches and crackers to save cash. gotta love it.
