Best way to get started with Xcode & Cocoa programming?

Hi, I have been interested in learning about programming and such since Apple has provided their Xcode tools for free with the MacOS CDs, but I currently know very very little about programming and such. I was wondering if anyone could recommend any good books or materials that could serve as tutorials for a begginer. I know that the Big Nerd Ranch and O'Reily have some good books out, but reviewers have commented on how they aren't meant for amateurs, so I don't want to waste my money on that, if it is the case. I also had thought about taking up a computer course in college to help me learn, but I have no idea which to take and if they are designed for someone who is new to the field. Overall, I don't want to be a programmer as a career, but I would like to learn to skills as a hobby and build my own little programs and so, so any advice would be greatly appreciated on which direction I should take.
