Any help/suggestions will be greatly appreciated

Anyone out there have suggestions on a way I could hook this all up without having to crawl around on the ground changing a million plugs? Are there such things mulitple spdif splitters? Can anyone recommend a soundcard that retains the quality of the audio when sent as a digital signal. I hear soundblaster leaves bits out. Can someone explain to my how I slave the speaker using spdf

The equipment:
Speakers- Active Tannoy's (with spdif input) needs to receive a stereo output from my mbox and also a stereo output from my pc sound card.

I will also need to send the 5.1 sound from my pc soundcard to a lo-fi 5.1 game speaker set-up.
