The last course (winter 2013) is IMHO a bit too lightweight, it avoids going deeper into some stuff that was touched in earlier courses. I dont's use storyboards so that's another minus for me, because everything is storyboards based. In any case this is solid course and highly recommended.

As for books the two I'd highly recommend would be the already mentioned "IOS Programming: The Big Nerd Ranch Guide"[1] and "Programming iOS 5" [2].

Ray's tutorials are also worth checking out.

This book was the most useful of the many iOS books I read when I was getting started.
