This is correct. Boot from your Mac OS X discs by holding C (or holding the option key, then selecting the disc from the boot manager). Then select an installation type (erase+install, archive+install or upgrade). Just make sure the discs are compatible with your friend's computer. (If it isn't an equivalent model iMac, they should be full retail discs)
To erase your hard drive, boot form the OS X CDs, then go to disk utility. You can remove data with added security by using the zero out feature too.
