Buzz, you will find the help here valuable and cheerfully forthcoming as I have since I converted. I have been to the well repeatedly and rarely failed to get a satisfactory answer, so a lot of questions you may come up with have been dealt with before as you can well imagine.
I would recommend you have a read through the following two threads at your leisure and you will get an idea of the breadth of problems covered. They were a great help to me. Welcome to the world of Mac!
