Most things should be pretty intuitive with OS X. There's really only one thing you need to know and that's that the red 'x' button in the corner doesn't always function like its equivalent would in Windows (to get the same effect you have to quit most apps in OS X... command + Q on the keyboard is the fastest way to do so). While on that note, the green button is not maximize on the Mac, it's resize to the right size... in other words, it makes the window as large as the window wants to be, but you can drag the triangle in the corner of a window to resize the window to your desired size. Other than that, there's really not much you can't figure out easily on your own. Enjoy your new MacBook, they're great machines.
