Surround Sound Help(connection to an Xbox), and my dream media setup

I couldn't decide what forum to put this in(since surround sound could also be a Home thing), but i decided that Music would be best.
Basically, I bought a $79 Logitech surround sound system a few weeks ago and hooked it up in my room. For the money, it's pretty awesome.
The sound is lacking though, it's fine, but the frequency response is anything but linear. Some songs are more noticeable than others. Either way, I've been looking at the Logitech Z-5500 THX Certified surround sound speakers. BTW, all these are 5.1, not 2.1 sets.
The reviews on youtube and elsewhere give it 5 stars, and some go as far to say that the sound matches $500+ units, saying its the best midrange speaker system around. The ten inch sub is appealing too(movies- watching The Patriot would become just that much more real because of the explosions). Reviews say that the satellite's sound is sharp, clear, and pure, no static or buzz.
That's definitely a big deal to me. So yeah, the Z-5500 set is $300+...and the others were $79...
I think it's worth it to someone who praises music like I do. If you listen to music occasionally, then you might not get where I'm coming from, but I listen to 3-6 hours of music every day, sometimes more.
MY PROBLEM:
I already installed the surround sound(the cheaper one) in my room, and it would be retarded to get another set. Not to mention a waste of time and money. I need money to buy the nice set. So, my brother agreed to buy it from me if I install it for him. He wants it to be hooked up to his Xbox 360. Good deal. However, I don't know what kind of output it has. I think its a Toslink Optical Audio output, but I'm not sure. The "receiver" on the sub has three inputs, a black 3.5mm female input, as well as a orange-red and light green input of the same type. These are the direct analog inputs to the speakers; it was a cheap set so they don't have an optical in.
MY QUESTION:
Assuming that my brother is still interested by the time I have the money to buy those speakers, do they even make a Toslink Optical adapter that will work? I tried google, but I wasnt sure what to search for.
Thanks.

Also, if anybody has the Z-5500 system, let me know how you like it!

My hopeful media setup:
Dell Inspiron 1501 laptop with vista
2TB Mybook External hard drives(two 1TB drives, either in a RAID setup or not, idk)
Videosecu VGA to Component Video adapter
32" TV
Creative Sound Blaster external 5.1 surround sound card
Logitech Z-5500 5.1 surround sound

Dream setup:
Mac Pro with dual monitors
some kind of adapter to get the video to the 32" TV above
Same surround sound
Same hard drives
Some kind of surround sound card

Basically the only difference between my (hopefully) future setup and my dream setup is the couple thousand $$$ of Mac and Apple stuff. Apple is so much better, but it comes with a price most of us cant afford. It's really too bad lol. For the first setup I only need the hard drives, the surround sound card, TV, and the surround sound to make it complete. Of course, theyre the most expensive parts...darn

Thanks!
