Kevin,
As a good rule of thumb, you should try to separate your cables by about 3 - 4+ inches from each other and then raise them 4+ inches off the carpet with something that does not store electrical energy. Where cables must cross each other, do this at a 90 degree angle and don't let them touch: place a piece of wood (balsa works great, so do wood paint stirring sticks from the paint store) or crumpled paper towel between the cables to hold them apart.
Good materials for cable supports are wood (balsa is great), paper (e.g., paper towel roll tubes or even crumpled paper towels) or ceramic (e.g., a coffee cup - but be cautious of glazing that would contain iron).
Tripods of wood dowels (three dowels held together with a loop at about two-thirds of their length) work well. Another fine solution is to suspend the cables with string (attaching one end to the wall and looping the other end around the cable). In my system, I have several cables lifted out of the way using masking tape loops.
The point is, effectiveness need not cost anything, as demonstrated by this very high-end, very highly tweaked, setup in this photo:

Consider trying the no cost avenue first and see if you don't get some pretty positive results. Certainly works here in my system.
Cheers,
