When I started shopping to trade in my NA car, I found one with 30k miles on that I missed by a few hours. I called about it and the owner told me that they drove away in it literally 3-4 hours before I called. Then I found one at 95k, one at 92k, and one at 60k. I bought the 60k one... they're like, all over the place. I had to drive about 2 hours to get this one, though.. so yeah look outside your area and be willing to go for a day trip.
I used AutoTrader to find it.
To OP: Dont use the drop in! Take out the stock tubing and build an intake with some piping and put an AEM cone on it. (Can you still get them $20 shipped on ebay?) You'll want the blower whine, it's part of the experience!
You'll wanna go for the 3.6" pulley first, the supercharger on your car is a Gen V which is loads more efficient than the Gen III that was on pre-04 cars, so you'll essentially get more boost out of a bigger pulley. If you can go knock-free on a 3.6, you can start modding for the 3.4.
I dont think you really need an IC for what you're doing, but I guess cooling the charge doesn't hurt at any boost level? I just dont know if it'll be worth the price tag. If you go for the 3.4, you might need it on the Gen V.
