My takeaway is that I guess different people look for different things. Because when I was hiring for a developer, I couldn't care less what your GPA was, and emailing the CEO certainly wouldn't have earned you any bonus points.
I looked for, well, relevant experience and a good cover letter that explains why you want to work here specifically -- as opposed to an obvious copy/paste job. (And, incidentally, the cover letter should be the body of you email message. It's unbelievable how many people attach a professional looking coverletter.doc to an extremely informal email message. Give me a reason to want to fire up Word and read your attachment. </rant>)
