Basic Mac user interface question

I’m a new blender user, using a macbook pro with a magic mouse. I’m watching the Blender Cookie interface tutorial, and none of his inputs are the same as mine. My “left” mouse button moves the black white and red crosshairs, my “right” mouse button grabs the object, and the mouse trackpad strafes the view horizontally, and vertically. How do I rotate around the object, etc.? Can someone help me get my inputs to match Blender Cookies?

That is the correct default setup for the mouse in blender.

In the File / User Peferences / Input, enable the ‘Emulate 3 Button Mouse’ option then use Ctrl+U to save as your default
Rotate view = Alt+LMB
Pan view = Shift+Alt+LMB
Zoom view = Ctrl+Alt+LMB

Much appreciated!
