TROUBLE WITH ITUNES 11.1.1 BACKING UP AND MORE

I have installed itunes 11.1.1.

Now syncing my iphone 4, it says i need 4gb more to sync. It ignores that I said only checked songs.

Additionally when i plug my iphone in, it bring up itunes. When I close it, about 2 minutes later it comes up again. close it comes up again. i know i can uncheck, come up when you plug in.

Has anyone had a similar problem? Any fix?
