New Owner In Missouri

[Artic93]

Hello, I purchased a 1993 Artic White/Black ZR-1 this week and I really love the car! I searched for months to find this car and I really think is was worth the wait. It has 14K on the odo, and is a one owner originally from California and relocated to STL MO. It looked to me that the car may have been sitting for a period of time, due to a few cobwebs around the gas cap! I bought it from FastLane Classic Cars , and I was amazed at the knowledge and great buying experience I had.
This is my very first Corvette and I know very little about what to look for down the road with issues that will arise. Lucky for me we have a strong Corvette Club in the town I live in and a well respected Corvette mechanic that works on the other 2 ZR-1's in town.
Two questions: Power steering is whining, and the car "creaks" when I turn the wheels in the garage...any ideas on these? Also I am waiting to drive the car very hard until the mechanic goes over the car well next week...any preventative things that I should do to a car that has such low miles and may have sat for awhile? And how do I tell what number the car is for the production?

Thanks
jason
