I have a 20" iMac Core Duo ('06) and its hard drive recently died. Luckily, I'm booting off my external firewire drive via SuperDuper clone. My question is can I purchase an additional firewire drive and use it as my backup drive and continue operating off my existing drive? Thanks.

Yes you can - provided there is a port free on either your iMac or the other drive, of course. Firewire has a max of 64 devices, IIRC, so you can add 62 more drives if you want to.
The new Mac Pro has up to 30 MB of cache inside the processor itself. That's more than the HD in my first Mac. Somehow I'm still running out of space.

Of course, one can't get close to the theoretical device limit. The practical Firewire bus device limit is far lower (I've heard), but certainly three or four Firewire drives are absolutely fine.
