Benoit,
There is no perfect format for everything so just try some stuff.
Blu Ray is smart enough to play just about anything.
Vegas is smart enough to allow you to edit just about anything.
Don't make your first use of the camera a paying job. I always take a new camera, get an hour of shooting, may a second hour with different setting, maybe all day with diferent settings, light, framerate, speed of subjects moving, etc.
Each time you change, record yourself saying what the new settings are.
Then bring it into the editor and compare the various looks. No effects, just titles to differentiate the settings.
Take it all the way to render and burn. Then you can really compare on a blu ray player and tv.
You will also have other items to play with regarding the 3 d effect, like focal point, do subjects converge in front or behind the tv, Is there enough light. (Active 3 d glasses only allow half the light to each eye).
By this point, you will feel more comfortable doing a second or third round of your own tests going all the way through production of a bluray.
This may take you a week or 4 to become experienced enough to actually do something for someone else.
