Most jobs don't call references anymore, and most workplaces aren't allowed to say much more than if you worked there or not. The best way to get a good reference is if you know someone who works there and if you give them your application to give to the hiring supervisor.

Professional-looking resume doesn't just mean it looks nice, it also means that you have your most important skills/abilities/experiences at the top of the list and that you have a professional-looking email address. Basically, if the interviewer only looked at the top thing on every list (and they sometimes do), you want it to be the best thing.
