Simple things are:
Chip, Exhaust, intake, suspension-the m42 is built fairly well and to get big gains out of it you have to throw money at it. Just keep the revs up (3500+) for maximum driving fun.
For more Hp/tq go look into a supercharger, I agree with thekid, the Downing atlanta I only hear good things about.
I also think the brake upgrades are probably a little on the overkill side unless you are tracking the car, a more agressive pad (hawk hps probably for street use) will probably accomplish what you want and you will spend less.
