Replying to 3D using Gopro HD

I've got two kinda major, and probably quite basic, questions that i'd like to be answered,

1. If I mount two GoPros at eye width apart, will they give me the footage that i'll need?

2. I've worked out that in FCP i need the video of each camera, exactly synced, on on v1 one on v2, what filters or effect do i need?

If found this website that kind of helps but would just like a bit more information.

Thanks,
