You have an auto.......dude you MUST get a CAI and tune from brenspeed. It will change the vehicle to 100% fun. The soft slushy feel of the trans shifting will be replaced with firm tire squealing shifts into second and third. It makes the car so much fun yet is still very safe. This is after I got a brenspeed tune and cai.......so cool.

On an auto a tune will help with the shift points.
If you want seat-of-the-pants power, but don't necessarily care about driving above triple digits, then go with a higher gear ratio, like 4.10.
If you want better sound, an axle back exhaust is a good place to start, then there's headers and offroad x/h-pipes.
If you're never going to supercharge, then an underdrive crank pulley will help... and then there are a lot of little things you can do.
