Oversize tires and/or different wheel offset can create the need to back up, but can also be caused by worn out shift fork. Ask the dealer to show you where you authorized the $99 check out fee when you dropped off your vehicle. If you did, pay it. If you didn't, don't. Almost all the extended warranties(even GM ones) have certain exclusions. Can't speak for yours specifically.
Wind noise and bulb are easy fixes(see other threads) you can do yourself. If you've got oversize tires/wheels, put stock back on before taking back to dealer.
