Firstly, your question would be better placed in the TelePresence section of the forums where these devices are more actively discussed than in the Cisco Cafe where you've posted. I'd suggest you move your discussion there.
If you do a search in that section, there are a number of discussions already on the SpeakerTrack cameras.
In short, NO, the extra microphones do not affect the functionality of the SpeakerTrack - they're purely for audio in to the SX80 endpoint. The SpeakerTrack camera only uses its internal microphone array to locate who is speaking.
If it's not working properly, make sure you check everything is connected as per the SpeakerTrack 60 Installation Guide.
