Yes, yes, yes make the recovery disks. Label them correctly and store them safely. Under W8 there is an option to create a system recovery, I recomend this as it is a basic tool for repairing W8. CD or usb, up to you just have a practice at booting from whichever media you decide to use, and make a note of the steps you took.
