Not at all. Unless you went to a top school, where you went to school becomes irrelevant after a few years. Where you worked and what you did become much more important.
Todd is right. After a couple of years, your school is much less important than what you've done with it during that time.
I would say that after a few years, even if you went to a top-flight school, no one cares. The only lasting benefit is the collection of connections that you made while you were there.
No, as someone doing a lot of interviewing lately, it really doesn't matter. YMMV, of course, I know more good programmers out of Drexel than Stanford, and am in Palo Alto!
It depends. If you're a rock star candidate, then no. If you're average to good, then probably yes.
