I have a Sony LCD, Blu-ray player, & Sony surround sound system. I use HDMI....

...Should I be using optical audio? I just want the best sound possible, but I don't know where to begin. Should I buy optical audio cables (Toslink)? Would they run from my Blu-ray to the Sony Surround box or from the TV to the Sony Surround Box? Or both? I just have the expanded basic cable package, so no "digital package" yet. I watch mostly the local networks, which I get in HD over an antenna. Would optical audio improve my TV sound or should I just worry about the Blu-ray sound?
Do I need a receiver of some type to go between my Sony LCD and the blu-ray player?

I Agree. The HDMI gets you a hi-def pic, and good sound, so you dont need that other cable unless you do for some reason....
