I don't know if you still need help but, I've used the Macintosh for eight years (starting with 10.5.5 "Leopard") and Microsoft Windows from 3.1 all the way to 7 and than 10. You can either reply here with questions or pop me a PM I'd be more than happy to help you out!

One neat trick is cycle through open windows by holding Apple Command and tapping ~

Of course most people probably use tabs even in things like the Finder nowadays.
