Does anyone know whether or not you can buy the Audi Sports logo that is on the Sports steering wheel or on the back of the new S4 for the front grill of an A4? Or even for the rear of the A4? I called my dealership here in Arizona (scottsdale audi) and they said that they don't sell that part......

Try the Audi Sport Key-Holder in Audi Boutique. Carefully cut off the strap and carefully saw off, file and sand to a polished finish the metal strap loop and you have a pretty good silver-like metal and red ceramic Audi Sport Emblem. Now this doesn't have the two silver bars, but still looks good. Mount it wherever you like; front grill, rear trunk, side of car just below the side markers (you'll need two, one for each side), etc.
Best of all, if you do have an A4 or other Audi model that has the Sports Package, then with this badge on the car, you'll be staying truthful in that you won't have an S4 badge on an A4, which I consider un-cool.
