So I fixed my problem, and all the replies did help in some way, again, thank you all. The solution to my problem was, believe it or not, something very simple. 1st, connected to original Mac, stopes the wifi sync to that computer. 2nd, follow backup instructions to new computer. ( note, with iTunes 11, you really don't need the left side pane, there are buttons right on the summery tab of the device). 3rd, and most important, on your new Mac, you need to give it a name. So, in System Preferences>Sharing, put a name up there in the top space (if you don't already have one). 4th, in Summery tab of device in iTunes, check the Sync over Wifi.
It all worked after that, and stoped syncing to my old computer.
