You need a PDF authoring tool that supports the Acrobat security model.

1) This is standard stuff, though there is nothing you can do to prevent a user from just hitting "PrtScn" to grab an image on what's on the monitor or just grabbing their cell phone and snapping a picture while the PDF is being displayed.

2) There's no such thing. All security is vulnerable eventually. It's only a matter of time to crack a password no matter what algorithm is used. The trick is that, today, with current hardware, certain algorithms are very weak and only takes minutes to hours to defeat. Others, take centuries. Now, 10 years from now, what will be possible can change and more algorithms will be considered very weak.

3) There is no such concept. A document is nothing but a file on disk and will never have an "expiration".

4) Not possible. A document is just data. There is nothing executing to cause it to delete itself.
