A/V cables and monoprice question?

I recently bought a Marantz receiver and polk audio surround speakers and now i need a 100' spool speaker wire, subwoofer cable, and 2 HDMI cable. However in todays world there are so many different brands, prices, and mixed reviews about cables that I just don't know what to choose. I would your opinion on whether monoprice cables would good for my system and if not what brand and or place i should buy. Thank You!
