I came into desktop publishing from a totally different
direction (was originally in school with an eye on hospital
administration!). So I can't offer any specific advice on school
programs but I do have some suggestions.
First, here's a collection of Links from our Graphic Design Guide
for schools with programs specifically for Graphic Design:

Do take some art classes if you can, even an arts & crafts type
class. The computer is merely a tool. DTP/Graphic Design doesn't
require you to be an "artist" but a feel for design/what
looks good/understanding *why* it looks good, etc.-- it helps
tremendously.
Other ways to enter the field other than a formal education are to
work in related fields -- printing, for example. Working the counter
at a Quik Copy shop can even be a good thing while you're in college
working on a design-related degree!
