At least you were charged less than the estimate of $650.
Hard to argue with dealer on MAF replacement if the computer had a fault code on it, you should of course get the old one to keep as a souvenier as well as the computer printout (I am assuming it gives a hard copy).
I personally thought the cleaning crap was just that.
I can't suggest an approach since I don't know your past dealings with the dealer but I would certainly take it back, complain and tell them to fix it. I am presuming you and the dealer were able to witness the symptoms and that they are repeatable.
