i struggle with the same thing, but have made some real improvement in the past few months. i'll echo what poloboy and jfelco suggested, being aware of your posture at all times is the most important thing. become obsessed with it... think about it while you walk and when you're sitting at work/class. eventually it feels more and more natural as your body gets used to it and the supporting/stabilizing muscles get more toned.

as far as workouts go.... work the trapezious and back muscles a lot. also, one of the most underrated physiological causes is sometimes a lack of flexibility in the hamstrings. in order to get a full range of motion, your back is sometimes forced to round out to compensate for a lack of flexibility in the buttocks/hamstrings. keep your knees locked and try to bend at the waist while keeping your back perfectly straight (don't do this for too long)... you'll see what i mean.
