SimplyFun,

I, too, have heard that coiling the speaker wire anywhere is not a good idea. It supposedly increases the inductance of the wire. (An inductor, after all, is just a coil of wire.) I just don't know how much it increases the inductance.

I've also heard that whenever one cable crosses another, you should arrange it so that they are perpendicular, but that's a little extreme (kinda like keeping all your wires the same length.)

Did you also know that you should never let your wires touch the floor? Luckily, somone invented wonderful products like this to solve that problem...
