Hello, I've really been wanting to get into streaming but I don't want the background noise of my voice chat be Curse, Skype, Mumble or Teamspeak to be heard through. On top of that I'd like so my microphone doesn't play through twitch.

I've been looking for a creditable source in how to separate audio, yet still nothing that I can relate to what I'm asking.

In short

I'm looking for...
Video game audio ----> to my headphones and to those watching my stream.
Voice chat and other audio on my computer ----> only though my headphones.

Headphones: Razer Kraken 3.5mm headset.
Microphone: AT2020 USB Condenser Microphone.

If you can help thanks, any information is appreciated.

Look into Virtual Audio Cable (VAC) or VB-Audio.
Unfortunately due to the way the Windows audio subsystem works, you can't just capture audio from one process. You'll need to set up a virtual device which the program plays audio to, set OBS to watch that, then set VAC/VB to also output to your actual audio device.
Also unfortunately, fewer games lately allow you to specify an audio output device, making it difficult/impossible to do this. You might be able to set up one as a default and configure your VoIP programs to use the virtual interface instead, and pipe both virtual devices (default and the one your VoIP goes over) through the actual audio device (your headphones/speakers/etc).

This is WELL outside the scope of OBS support though; you'll have to pursue it with the support for the virtual audio option you end up using.

As far as removing your mic, just click the mic icon to mute it, or set the mic device to Disabled in the OBS settings.
That's going to end up being a very boring livestream though, without streamer interaction. Might want to consider recording locally and going for more of a YouTube Let's Play approach instead; would appeal to a wider audience and allow higher quality video to be used, not being required to happen in realtime.

Those are the two most common ones. VB-Audio is free but more limited, VAC is a paid program but is more flexible.
