Color/Luminosity Range and pulling Keys

Ok, so I am messing around here in Pre-Production on a project and had a quick question.

Basically I am shooting a short film, and I am almost 95% sure I am going to do all of it against a greenscreen, the whole film is boarded out to 62 shots, that will probably increase to 80 before I see a final cut. Of those shots there is (adding this up today) going to be around maybe 15 different distinct camera setups, 20 if you count a couple "zooming in, can we do those lines again please" with the actors just to get some extra footage to play with.

From the tests I have done this certainly adds a lot more work in post (not TOO much more because I would be color grading the thing in its entirety anyway) but it gives back about a million times more control over the picture and how I want things to look.

Since the look of the film is almost entirely setup in post, I want to get the most detail out of the camera that I can (HVX200a), I don't necessarily only mean line and edge definition, I am also referring (moreso actually) to color depth... I basically want to have as much range in post as I can possibly get to be as open with color and lighting as I can.

What are the settings I should be looking at on the camera?

I am trying to light the greenscreen well, and then put a nice balanced amount of light on the actors, using as little shadow as possible since I can easily crank it all up/down when/where I need it in post.

Anyway, here is the first look design test, I am still working with it, I want a bit less contrast in some areas and there will be a few more layers involved in the final, a lightray pass and some dust, and a couple extras in the BG, just so you all have a visual along with the wall o' text...

Any input, even if it isn't relevant to the topic is welcome.

tl;dr? Should I have summarized this or is there really 50 people browsing this forum at any given time that don't have the time/will to help a brotha out?

We've shot a lot of greenscreen; generally, we keep the settings all at about 0, except for master ped, which we like at about -5, and chroma, which we like at about +3. Might want to put the detail down a few notches, like -3 to -5.

Use your marker; light the greenscreen at about 60 and your people's skin around 70.

1080/24pA.
