Yeah, I keep wanting to help out with Camino too, but it's just so far beyond me (I'm also a just-beyond-beginning programmer), and you have to learn so much about the specific code before you can understand it enough.
My approach has been to get a good Cocoa programming book, read and do the tutorials for the first few chapters, and then jump in and start working on my own small application while using the book as a reference. That way I'm working with a code base that I understand....
