Question about hdmi and headsets with ps3

[Hunterpower]

So, i'm looking to buy these:
http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER
and http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER

so i can hook my ps3 up to my 1080p monitor, but i also want to use the headset for sound. is it simply plug and play, or do i need more cords?
insight would be appreciated
edit: and, i didn't see anything about it, but if the xbox version isn't compatible with ps3 any reccomendations for ones that do?
