The real advantage of performance pads like EBC is thermal, and unless you're on a track you're unlikely to ever be near the braking temps where you'd see a benefit. With the semi metallics you'll get increased rotor wear and more brake dust, may as well go with ceramic.
Also, drilled/slotted rotors are not needed with modern pads which don't produce as much gas when hot (if you ever got them that hot, see above). Mostly they just make more noise.
