Get a good patternmaking and an everything-sewing book. My degree was in fashion design and that was the only book I kept. Honestly, I think you need the following classes, though:
1) computer classes so you can get used to Photoshop, Illustrator, WebPDM, MicrografX, U4ia, and others that companies use on the job. If you don't know these, I think you'll really have a tough time getting a job.
2) draping and sewing classes: you need to know the human body and draping and fit is a function that technical designers need. Sewing classes because you need to know how clothing is constructed. Plus if your boss says "sketch a blouse with a French seam/set-in sleeve/pintucking/shirring" will you know what that is? You won't sew on the job but you need to know these things.
