2d animation staples like exaggeration and anticipation of motion can be achieved in 3d 'by just moving controls all over the place'. you just have to be familiar with the way things work. one of the best ways to get slight overmovements is by tweaking your animation curves in the graph editor... by moving tangents to change the way something eases-in or eases-out (or oversteps its keyframe value), you'd be surprised how easy it is to not only create slight (or even dramatic) overcompensated moves, but also to create them fluidly.
