Because I don't have Leopard yet, I don't have Xcode 3 so I can't answer your Xcode 3 questions. You can still ask them if you want, if you don't mind the response "I don't know". Apple has an Xcode mailing list where you can ask Xcode 3 questions as well as questions on other Apple developer tools like Interface Builder.
I will post on the blog when I get Leopard, also known as Mac OS X 10.5.

I have a new article available that provides an overview of the technologies to learn to write Mac games. The article was motivated by a discussion that has been brewing on Apple's game development mailing list for several list. The discussion revolved around Apple's lack of support for games, and one complaint was that Apple did not have a game library like DirectX. Without a game library getting started with Mac game development can be difficult because he or she may not know where to begin. My article helps them know where to begin. If you're new to Mac game development, check out the article.
