a few more ponys for my pony car

Recently bought an 04 GT with the 2 valve 281. It is setting bone stock right now. I am NOT looking to add massive power. Only 40-80 at the wheels. This is my daily driver so I am not willing to sacrifice driveability, reliability, or mileage. I figure a cold air kit and a chip are musts but after that what should I consider?

Thanks for the advice. I know it will take nearly every bolt on I can come up with. Thats the fun part. I always have a next project. There is the option of major power adders (N2O, supercharger, turbo) later - much later. Right now I am just looking for specific brands, models, or styles of boltons that work better with this car. Gears are a must as the limited slip that is factory is limited in its workings (sometime instead of 2 pretty stripes I get a peg leg) A friend said 3.90s which are hard to find in that 8.8 and another said 4.10s. I had a roommate in college with 4.10s in a fox body and there was no way I would drive that around town while trying to sip coffee. The friend who suggested 3.90s also suggested a programmer with presets and a touch screed that would allow the driver to change computer settings on the fly. He couldn't remember a brand name or model. Anyone have experience with a tuner that has a touch screen and preset power levels. If so; which one and is it worth it as apposed to one that can not be changed by touching the screed?
