before you touch the car let's scan it...
The 3.4 pulley may require some additional modifications, good things to look for are a used set of 1.9 rockers, you can get the first generation for about 200 some odd dollars, they really raise the curve, so racing after 50 isn't a nightmare.
The 180 T-stat is a good idea, it lowers temps alot and fights the car's will to pull timing. Not to much effect on the gas mileage.
I'm not a fan of the SLP cold air box, but, for what it is, I guess its OK.
HTH,
