Have a look at black diamond discs and pads I've just put a set of pads on standard discs and the difference is night and day, ebc seem to have mixed reviews on subaru's for some reason so although I've used them on other cars I thought I'd take a punt on something different. Maybe go braided lines and a brake booster for extra feel
As for handling, what's your ultimate aim ? Have you considered just upgrading bit by bit ? Maybe start with droplinks & maybe a rear arb with proper geo set up and see how you get on, that way further down the line you can add springs or coilies, alk, etc etc if you feel the need.
