J Irwan,
For improved brake feel, the first things to try are braided stainless steel lines, then a better pad compound (Porterfields had great feel on my car), and finally make sure you have the system bled perfectly. I'd do that before spending major $$ on different calipers or larger brakes. Guido's setup from StopTech is awesome, but mainly gives you fade resistance thanks to the gargantuan rotor size (350mm, I think - wow.)
Oh yeah - ATE SuperBlue (or Type 200) is the hot stuff for street use, it doesn't require changing every few months like the race-only stuff. In a pinch, Valvoline SynPower fluid is almost as good, and much cheaper.
