I agree with 4.10's as well. I have a 98 GT with 3.73's and wish I would have went with 4.10's. DON'T FORGET THE SPEEDO CALIBRATOR! It's very easy to install and your odometer will thank you.
If I had to do it all over again with a 96-98 GT, I would postpone the rinky-dink bolt-on route. Here's what I would do:
1. Gears
2. Head-swap
3. Intake manifold
4. Vortech supercharger
5. Tires, rims, suspension and bolt-ons
I think most people here will agree that you will see a solid performace gain from each one of these steps.

If you could do that and still keep your engine, i would be very surprised. When you do the 99+ headswap, it raises your compression (12:1 I think). If you then bolt on a supercharger, your stock block will die. In order to do that, you would have to rebuild everything inside...forged everything...I don't even know if the stock block could hold that kind of compression.
Your best bet is to choose one or the other. The headswap is about 1.5k for around 50-60 hp, where as the supercharger is 3-4k for 25-50% more hp. Depending on your budget and what you feel like doing in the long run, those are your pretty good options.
Check w/ hammer, he and stoplight seem to be gods of the bolt on chargers...they will know best.
