You can't use the standard keys, obviously, since they are used for your backlit keyboard. You will just have to change them. Right now I have the fn key as my "tile all windows" button, F11 as "all application windows", F12 as "show desktop" and the bottom left as "show desktop" and bottom right as "tile all windows". It makes for a pretty nice Exposé setup until I someday find an awesome multi-button BT mouse to use. I really want one of those Kensington studio mice with the touchpad scroll, optical tracking, etc, but the dang thing is RF instead of BT.
