if she is a 200 pounder you have to stiffen the spring because you are probably bottoming-out (the shock). im exaggerating (and only kidding about the extra weight) but you get the picture.
if the bumpiness you are referring to, is something else, try backing out on the compression damping. you want to be careful because changing the damping can screw everything up quick. do one click at a time on just the compression or rebound damping, and see how she feels. if thats not it, return the damping settings to the way you had it, and consider changing shocks.
playing with spring preload can make quite a difference, but i would try the damping 1st.
