Welcome friend. The options are limited only by your budget, but the LS motor is a beast. You can check the ad section for intakes, headers and everything else you may need to excel.

Welcome! Is the car stock? A lot if guys will start with a higher flowing air lid such as the SLP. A catback exhaust is also one of the first mods a lit of people do. Long tube headers will give you a very nice gain in power. Also, do a search for the free mods. The free ram air mod is a must do.
