1...i keep reading here that mobil 1 motor oil/filters are the way to go...is that mobil 1 synthetic that i keep reading about on these posts ?
2...should i be changing any other oils(tranny/diff, etc.). if so, what brands and oil weights should i be using ?
thanks in advance guys for the always useful info !!!

You haven't messed up. Mobil 1 is recommended by GM this doesn't mean you have to use it. Mobil 1 happened to give GM the right $ for advertising. Had another oil company won the rights they would be GM's recommended oil source.
Synthetics were developed for high performance engines and designed to give you longer life through oil changes, although standard oils have come a long way in technology. As long as you use SAE oils you'll be fine. The oil life indicator on the GTO measures engine revolutions which generally notifies you around 7200 miles for its change. This is just a guide, how you drive will dictate your oil change out intervals.
GM recommends 5w-30. It's on your oil cap. You can get away with 10w-30. As far as filters, go with a top brand, Mobil 1, K&N are two at the top, there are others, people have preferences.
There are other good quality synthetics out there. Again, people have their favorites. You spent good money on your car, oil is the cars life blood feed it with good stuff.
Personally, I change my oil every 5K and rotate the tires at the same time.
As far as transmission, differential changing.... follow the recommended servicing schedules and use good quality synthetics as outlined in the manual.
