I need to boot the ultimate boot cd from an usb stick. Do I just copy the iso image to the usb key?
How do I make the usb stick bootable?

I believe you need bios that can boot USB, or some intermediate bootable media to call it.
We get asked this all the time. Maybe we should make it part of the FAQ.
A USB drive is a hard drive as far as the system's concerned. Booting from it generally means either installing on it like it's a hard drive, or using some special arrangement a particular distro might have for booting from USB disk.
None of this is necessary for what you want however which, last I checked, was running memtest86. You can boot a kernel with kexec. Just find the memtest86 kernel inside those ISO's and kexec into it.
Have a look at Infrastructure/Fedorahosted-retirement - Fedora Project Wiki. This works on both Windows and GNU/Linux. Can handle other distributions besides Fedora and Sugar if you know what you are doing. There are a number of forks such as Mandriva Seed and Sidux liveusb-creator.
