Learning some iphone development basics

Got a hold of a mac recently, as of now I'm trying to learn a little iphone development by following a book: Iphone App Development - The Missing Manual, the book is quite good, however I'm to anxious just to follow, for some reason I feel it is going too slow at times.

Since I've never coded Objective-C in the past and I'm a complete n00b in Apple territory I have to get calm and try to read the book, I guess I'll try to give it a shot and in parallel try to code every example in Xcode, maybe that way I can feel more at ease with the books pace.

Don't know if having a book is the right approach Apple's ADC has lots of getting started info and videos, tried to watch some of them but got bored too quickly don't know if it is that I'm to anxious to have something working or is something different screwing with me?

I try my best to get this going, need some extra cash my little boy is aiming for school next year so I definitively could use some extra cash.
