Email, File, and file content, Rights Management (office,pdf, other..)

Hello,
I'm looking for one or more solution for managing security document and content of the document. We are in an environment (windows 2003).
I must:
Protect Office documents, PDF, DXF ... and any type of document.
Protect against copying partial or complete "copy paste" and "print screen."
Manage impressions, which has the right to print or not.
Possibly watermark documents.
Monitor the activity of a document and a directory.
Protect against physical copy.
Possibly Encrypt and sign the documents.
Possibly Set lifespan of a document.
Protecting mail: digital signature, protection against copying, transfer, printing

That everything is managed at the level of working groups or directories but not in the document.
I have some ideas but would like your opinion.
Thks
