Logitech Z-5300 Sound System On Macbook

Ok i have a new black macbook and i wanted to know what i need in order to use my 5.1 logitech sound system. I've tried looking it up online, but i have gotten many different answers. I want to play music and watch dvds with all 5 speakers playing. There are 3 plugs (black redish and green, but i only have 1 plug for headphones on my laptop.

Thanks...
