Ok finally got all this together. Thanks for all the help and guidance from everyone. Will post a video for everyone to see in a week or so.
Biggest over all challenges…
Connecting the ATEM via the router so I could use it on the network
Getting the HDMI signal over anything longer than about 25 feet… 1 run was about 40′, other 2were about 30′
DA STUFF…

Samsung Sync master Ex2220 (second monitor to the MAC)
ATEM Black Magic
Viewsonic LED HDMI 1080p VS13814
1 Panasonic GH2
3 Gopros HD2
3 HDMI via cat5 connections (could not run HDMI over 50 Cables)
Behringer Ultra Match SRC 2496
Netgear Router WGR61

RCA to BNC (cheap and works awesome)
Audio Source Power Amp with 2 polk audio speakers connected 2 sony bookshelf speakers also so I could fill the dance studio with sound.
