I use this for the sub:
http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=181-644

I have monster navajo white (got it cheap) on the fronts and center (16ga at 10' each) I have RCA brand 14ga on the surrounds - 35' runs.

Most any cable is good - look around at PartsExpress or go to Home Depot.

12 or 14 guage wire will be sufficient.
