There are many standard i386 development and security LiveCDs that will run fine on amd64 computers... but not many specific amd64 LiveCDs. Is there any specific reason you need to use amd64 vs i386?
Also, all LiveCDs include the tar program, "tar" is similar to "zip", so it's not exactly an application but more a collection of files. Any LiveCD should allow you to extract a tar file, either from the command line or double-clicking on the icon from the GUI.
