New website using the book module

I am in the process of developing a website, and I found Drupal after searching for "collaborative book". Right now I have Drupal installed, but finding the information that I need is strung out and hard to aggregate. I was hoping for some guidance in how to get Drupal to fit in my (albeit, flexible) paradigm; or if there are modules that exist for what I want to do. Here goes:

- One collaborative book to begin with. Multiple independent books could exist if the site gets popular.
- A menu structure for the book should have the chapters expanded, but pages contained underneath are hidden.
- The chapter structure needs to be "locked down" so no additional chapters can be created.
- When a user edits a page, versioning of that page is stored and is easy to navigate through.
- An administrator needs the ability to restore a version as the "live" version on the site.
- The ability for an administrator to "lock down" a page or chapter as a final revision. (I'm unsure whether the core security roles can accomplish this or not.)
- Users can attach a single image or multiple images to a page or chapter. Basically for illustrations to accompany the text.
- A voting system on the revisions would be great; to either a page or a full chapter. Perhaps a simple poll could accomplish this. Can a poll be attached to a page or chapter?

When I say "attached to", this means there will be descriptive text but an image or poll can be associated with it. Much like a forum can have an image uploaded and associated to a post, or a forum post can be of type poll.

I'll continue researching to try and answer my own questions. Again, this post isn't a "help me or I can't move forward on my own" in nature. I was hoping to have some participation to cut through the fat, so to speak, on all the strung out information I'm wading through right now.

Thanks
