Congrats man! Always cool to see another Kentuckian on the boards. Make sure you check out the 05-10 GT section, I'm sure you'll find a lot of the info your looking for on there and don't forget about the search function. That will get you some points with the other members on the board. Enjoy her and don't neglect her and she'll perform like a champ.
As far as your future upgrades are concerned, check out AmericanMuscle.com and LateModelRestoration.com. Within those two sites you should probably be able to find nearly everything you are looking for.
Oh and by the way she looks very pretty
