I wholeheartedly agree with Ron.
Unless portability is crucial (in which case a field camera will serve you well), a monorail camera is the way to go. Hands down the most versatile camera system, and many pros (especially in landscape/architecture/product photography) still use them, whether with film, or with a digital back. My personal favourite is the Sinar P that I use in school, but the Omegaview 45s are damn decent, and usually dirt cheap.
90mm, 150mm, and 210 mm are probably the best focal lengths to start with.
EDIT: and, as the book is a recommended text in my program, I would also suggest picking up a copy.
