From my experience here, I would add:

7. Don't just direct everyone to your web site. This ties in to some extent with #2. If you're not meeting the students, setting up interviews, holding info sessions, etc., then your physical presence is superfluous and distorts students' expectations of career fair.

8. Don't say you're looking for students from all majors. You won't get taken seriously. Maybe your company really does have openings in every field this school offers, but USPTO is the only employer I've seen who can even come close to justifying this claim.

It's also worth noting that students (here, at least) talk to each other about the recruiters they've encountered. Students remember really good recruiters and those who make serious faux pas.

Why not? If you're smart and are interested in programming, it's quite possible that I am willing to "take a chance" on you. It doesn't really matter if you studied data structures or English literature; CS majors have as much experience writing real software as English majors do.

If you're really worried about students from "all majors" being unqualified, then it seems to me that the answer is requesting a small coding project ala FizzBuzz to seperate the wheat and the chaff. Those who can, do - those who can't... do something else.

Around here, students generally major in what they want to do for a career. It's not that a person isn't capable of doing things they didn't study -- they just aren't likely to be all that interested.
