As for the whole intellectual copyright thing, that isn't the reason we cite. We cite sources because it provides a basis to our argument, it shows we haven't just drawn it up on the back of a cigarette packet. That's why you have to cite everything you draw upon, even yourself. Welcome to academia!
Oh, and most things you submit to your university will become their property. This was definitely true for my dissertation, and I'd assume it applies to other works too.
