To perform an Archive and Install just pop in your Mac OS X install disc and double click "Install Mac OS X" and your mac will reboot to the install screen. From there proceed to install OS X. There will be an "Options" button, press this and you will see the option to "Erase and Install" or "Archive and Install".
Proceed to the next screen and press the "Customize" button and you will have options to uncheck print drivers you won't be using and those useless languages as they eat up a lot of hard disk space. After that continue with the install. Skip the function that checks the disk, it just takes too long. If you remove those language packs and print drivers and skip the disk check the whole process should take no more than 30 minutes.
