Regarding the hyperbolic (etc) classification of PDEs: you may want qualitative theory instead of (or in additon to) number crunching. I'd suggest stopping over at UC Davis, where I count at least half a dozen PDE folks in the applied math program (more if you count the turbulence and fluid dynamics folks). Never miss an opportunity to buy a mathematician lunch :-)
