What gears do you currently have? If you dont know go look at the door sticker and see if it says GU2 or GU5. GU2 is 2.73 and GU5 is 3.23. If its 3.23 I wouldnt even worry about gears.
Next is your budget, what can you spend right now?
A stall converter is the hands best down mod for an auto and will provide the biggest gain. The size depends on what you do with the car and how much do you care about how it drives? A 3200 stall will be pretty good in a DD and they can be had for around 400 new if you want a budget converter. Otherwise a 3600 will be a tad more loose feeling but will provide more performance.
Speed engineering sells a nice set of 1-7/8 headers (dont get 1-3/4) for about 300 bucks and you can add a y pip to that to mate up to your existing catback. that whole package will be about 380.
Finally you can either pick up a used ls6 intake if you can find a deal or go get a new dorman aftermarket replacement and just do some minor porting on it to outperform the stock ls6 intake. That intake is right at 280 new.
If I was doing this I would first add a set of headers and y-pipe, then add the intake and lastly the stall. Now normally a stall would be first but your car is mostly stock and the other mods wont necessitate a tune whereas a stall will so if you do the others first you can still drive the car around like normal.
