Well, as to wire to hook-up speakers, the most cost-effective move, considering shipping charges, is to deal with a local hardware or electrical supplier of the Home Depot type, which I use when I need some lampcord. For good info on wiring speakers from a veteran audio professional you might study this .

For interconnects, MonoPrice can't be beat for cables that do the job as well as anything and at very reasonable prices.
