OK, so this is the resume I am going with right now:
I decided to go with Times New Roman 11 for the main content and 14 for the headers. That gave me more space to work with. I am going to apply for a few jobs with this one and see how it goes. Thanks to all who gave me feedback and advice. If you have more though, don't hesitate to throw it at me. This is by no means a final version (of my resume, that is).
