We strongly recommend headsets with integrated microphone to reduce any echoes. Although USB headset-microphones (around $30) are preferred (to reduce noise), analog headset-microphones (around $15) work perfectly as well.
Example of USB headset-microphone: Logitech 'ClearChat USB Pro'
Example of External Echo-Canceling Microphone: Blue Yeti

We recommend higher quality webcams with 2+ MegaPixels quality.
