Answer 1

If this is server side (non-interactive) use of the Word application itself is unsupported (but I see this is not applicable). So either take that route or use the OpenXML SDK to learn the markup needed to create a comment. With that knowledge it is all about manipulating data.

The .docx format is a ZIP of XML files with a defines structure, so mostly once you get into the ZIP and get the right XML file it becomes a matter of modifying an XML DOM.

The best route might be to take a docx, copy it, add a comment (using Word) to one, and compare. A diff will show you the kind of elements/structures you need to be looking up in the SDK (or ISO/Ecma standard).
