As I've posted before, Victor Navone is a folk hero for those of us in the animation world.  He made "Alien Song," a classic short film (and it is short, only one minute) that went viral, and landed him an interview at Pixar.  Now he's one of their main dudes.  His website is one of pure altruism for upcoming animators, and his tutorials should be curriculum for any animation program. Here's links to Navone's tutorials for anyone with a fear of Splines in the Graph Editor.
