DHLabs, Zavfino, Morrow Audio, Anti-Cables....all make excellent cables at affordable prices, and at different levels of cost and quality. Great places to start
Power cords: whatever came with your system, because anything else won't matter one single bit.
Speaker wire: any well made 12AWG OFC. Monoprice and Blue Jean Cables are cheap and effective. A coat hanger would literally sound just as good as any expensive snake oil brand but may be tougher to work with. :)
