Awesome idea on the brakes, like scheides recommended get the rotors turned and throw on decent pads. I wouldnt do the brake lines unless you are expecting to get a fair amount of heat in the brakes then it makes sense, most street cars will never get that much heat. The biggest difference you are going to feel is getting new fluid, that alone will make the pedal much firmer just from not having old janky watery fluid. On the silver x, bleed the factory stuff out @ 10K and noticed an immediate diffence in the pedal feel.
