Thats all true to a certain extent, but the qualifications get you in the door to prove who good/enthusiastic you are. In the current climate, where employees will have loads of CVs on their desk, they're going to get picky.
I'll also say that I work with a lot of people who have many different qualifications, often nothing to do with computing.
Passion, enthusiasm, ability to learn quickly, flexibility are really key I think.
