Congrats on the car! You will love it.
I am of the thought process to just drive it for a while and get a real feel for the car. I know I have bought various cars in the past and immediately started modding them just to turn around and replace the stuff because I wanted to either go a different direction or found better stuff.
I have to agree with GarageMadness and his advice on painting the utter.
There is a lot of information on here and friendly venders. Look around and you will probably find just about any topic you are looking for.
