Writing more complex text into Writer using pyUno

I am trying to export some text from Python into a Writer document which I created according to these instructions.

For example, using

cursor.setPropertyValue("CharHeight", 20)
cursor.setPropertyValue("CharWeight", 150)
document.Text.insertString(cursor, "This Is Heading One", 0)

I can make a line of text look like a heading, but it’s just text and not an actual heading. What property values do I have to modify to generate a heading line that’s picked up for the TOC?

In general, where is the documentation for the properties, and how to navigate the Writer document in general? I’m having a very hard time digging up anything at all!

As for the first question:

cursor.ParaStyleName = "Heading 1"
document.Text.insertString(cursor, "Heading Text Here", 0)
document.Text.insertControlCharacter(cursor, uno.getConstantByName("com.sun.star.text.ControlCharacter.PARAGRAPH_BREAK"), 0)
cursor.ParaStyleName = "Standard"

This works for using existing paragraph styles. Don’t know (yet) how to create new paragraph styles.
