Sony Z5U: Looking for detailed settings to get better film look

I have owned my Sony HVR-Z5U since the beginning of April this year. So far I am mainly shooting events, legal depos and web videos, but I want to start getting closer to using its advanced features to try to get a better "film look."

What I was hoping for this post is that someone who owns a Z5U and uses it to make indie films, or has a very good understanding of how to tweak the deep menus in the picture profiles can give me some suggestions on building a setting that works well for professional film-like results.

I use Sony Vegas Pro 8.0 and 8.1 for editing, and I recently got Red Giant's Magic Bullet Looks 1.2 for color grading. My goal is to follow the advice of a film maker and shoot rather flat in camera and preserve a lot of detail in the shadows, and then get the actual "film look" in post. So I'm not so much interested in trying to create the "film look" in the camera, but I do want to know more about the "cinema gamma" settings in the camera so I can get those as close as possible to what I will need in post-production.

I have been a professional broadcast news videographer for 10 years but went freelance a year ago, so I use all manual controls and have a decent kit of gear, and I shoot pretty steady already. I realize that a good bit of the "film look" is shooting in 24p, correct camera movement, lighting properly, steady shots, and avoiding zooms. Mainly what I am going for now is, how do I shoot for the film look with my Z5U with a workflow that assumes half of it is in-camera, and the other half in post?

Cinematone 1 and 2 are nice, but I am afraid they do too much in camera, crushing details that I might need later in the NLE. Should I just shoot with PP3 or one of the others? Or is there a really good custom preset recipe that is well suited to shooting video that looks a lot like film when you run it through Magic Bullet Looks?

Thanks so much in advance for any advice, whether personal or if you could point me to a link, chart, thread, book, website, etc., where I might be able to get this answered.
