Hmm, sounds like he used tinted clear or something or your cars body was slightly lighter than the original color they used when your car was new. That usually is due to sun damage as I had that problem too...
For the orange peel, tell them to wetsand it and buff it out. If its a reputable shop they should have no problem in doing that. If they refuse, tell them to refund part of your money so you can find a quality detailer who can do it for you
