You don't have a USB keyboard or mouse? Maybe find an old set from someone's old iMac or something? Even an old iMac keyboard and an iPuck will be enough to get you up and going.
Failing that, nip down to your local PC store and buy a PS/2 -> USB adaptor, i'm assuming that much like me, you have an endless supply of PS/2 keyboards. I'm using a DEC keyboard from 1994, and a MS wireless mouse on the iMac via a PS/2 adaptor, and they both work perfectly.
