Stick with the live. I had an sblive platinum 5.1 and bought an audigy mp3+ and can hear absoluteyly no difference at all. None, zip, nada. $100 bucks wasted. As for firewire, well, I have no firewire devices so im SOL. Actually, I preffered my platinum 5.1 as it had legacy drivers that worked in WinME. The legacy drivers for Audigy dont work with WinME. Its not a big deal for most people but I still play a lot of old games like the original tombraider and alone in the dark 1 2 and 3 and commanche 3 and such.
