Recording game footage & audio.

Okay, first off I have no clue If I'm posting this in the right place as it's PC hardware, software and audio/visual related so I'm hoping it's okay to post here.

I currently have an AVermedia C985, ASUS Xonar Soun card & Razer Megladon as my setup. I can record my game footage easily with the audio from teamspeak or without it by using a stereo mixer and sending everything back through my headset rather than what it's recording from the sound card.

My issue here is that I'd like to be able to record my game sound, my voice and the Teamspeak audio and I have no clue how to go about doing this, can anyone give me some pointers please?
