Welcome to CEG, and more importantly... the eastern forum.
My only advise is to study the maintenance forum and identify what things to look for that may or may not have been done to your new ride.
You definately got close to the right driveline choice... once you've had some fun, check out the 3L forum... if you're REALLY interested in modding
Good luck to ya, and enjoy your stay. Remember to search for your answers before posting.. not so much here in the east, but for any of the main forums, there are several post whores who will give you paragraphs about why you're such an idiot for not searching, yet the answer may be as simple as a tiny sentence.
There is talk of an up comming meet, altough those plans have yet to gel. (although i do think a large eastern forum meet is long over due)
Cheers!
John.
