If you have the time do the Santa Fe workshops. http;//www.hdworkshops.com
Barring that get in touch with the rental house that you intend to get your
camera from and do a hands on.
Some things to look out for are back focus and focus issues, lighting for
shadows while preventing over exposure and choosing 23.98hz or 29.97hz
for the look or final exhibition of the project.
Good luck,
