I once received a resume on hot pink paper. It hurt my eyes so much I couldn't read it. I just gave up. I should not need bifocals to read your resume. Check for typos.
Proof reading is a good thing.
Speaking of cover letters this is where most people crash and burn. If the tape is a collection of what you can do and the resume is a synopsis of what you have done then the cover letter is the reason why someone wants to look at the other two. I suggest you include two or three references with your packet. These days news directors do not have the time to eat lunch never mind search out references. Make sure you tell the people you are using as a reference that you are using their name.
