Easy way to replace CD's that came with my MacBook?

I have been moving the past few weeks, and as I finished up unpacking I realized that I cannot find my case that held all of my important CDs. Namley, the 2 disks that came with my Mac, and the iLife '09 upgrade I ordered. While the iLife CD is not a big deal, from what I understand with the $29 Snow Leopard upgrade, I need to have the CDs that came with my system if I ever want to do a clean install.

Is there any easy way to go about ordering any of these CDs? Or am I just out of luck?
