Could someone please tell me what this package is and what it entails. Im trying to figure out if i have this package or not because i need new rotors and there are the basic kind and the 1le package. My car is a 1990 trans am gta with the 5.7L

That you have a 1LE is very unlikely. Check the front rotors--11.7 with dual piston alum calipers is 1LE, 10.5 with iron calipers standard stuff. Should you wish to know more about the 1LE, check 1LE.net. It's possible also to have 10.5 fronts with the larger rear rotors and single-piston alum calipers on 89-92 cars. The following link will provide pics of the front and rear 1LE rotors/calipers:
