Probably put this in the wrong category, not sure where it goes.....

Anyways, I just bought a new gaming headset with a mic, but I've never used one before and I have no idea how to use it. A few questions:
1. How can I split the audio between the stereos and my headset? I would like to have things like skype or teamspeak on while I'm playing, but I don't want to get all the voices along with whatever is going on in the game all at once, I'd like to have skype/teamspeak coming in through the headset, while the game is going through my stereos, how would I do that?
2. How much background noise will the mic pick up? I have a lot going on where I am, if the mic is picking up everything around me it will just be a mess.
3. On and off switch not working? My headset has an on/off switch on the volume control thingy, but it doesn't seems to be doing anything.....
The headset is the Gamidas Hebe.
