The last time I installed from a USB key all I did was:-
wget http://mirrors.dedipower.com/centos/5.4/os/i386/images/diskboot.img dd if=/path/to/diskboot.img of=/path/to/usb.key
That only gets you a bootable USB key, but without the packages. May be all you want, but not really all the article, or the alternatives, cover.
