CocoaDev Central is a great initiative to get useful information about specific Cocoa programming topics.
I also found a great tutorial to Xcode & Cocoa for absolute beginners on CocoaLab.com : CocoaLab / Become an Xcoder
I highly recommend this site to anyone who's a little bit lost in the Cocoa jungle. It may sounds a little bit too easy at the beginning ("what is a variable", OK thanks...), but later they explain the Cocoa Classes, and how to get info about them.
