I recommend to search for Delphi tutorials, manuals and books especially for the beginners. They are much better organized. Tutorials don't have to be based on most recent versions as the basic features have not changed. There are really good ones for Delphi 2, 5, etc.
I'm not blaming Lazarus people at all. Now I'm more comfortable with Lazarus wiki as it contains only the gist. But for beginner, it is not easy to understand. Delphi is paid product anyway, has longer history and been taught for long time in university or at other places.
