For a starter in FM6 (and this is the way I developed my numbering strategy): 

Set up the chapter and part number to use the same variable: <chapnum>.  

Set up the chp and part number to use the same para tag. 

From the book file: 

Highlight the Part and manually set document number in the Chapter list box.  

Highlight the Chapter immediately after that Part and manually set the document number in the Chapter list box.  

Highlight the contiguous chapters after that Chapter file (within that part block) and select "continue from previous." 

Repeat the process for the next block of Parts. 

You must set numbers for the "first" Part and the "first" Chapter of each division manually. 

Note: you can also set the Parts division with the <volume> variable, but for my needs, our books are set up with volumes. I needed a way to set up the books numbering structure as volumes, parts, chapters/appendixes. 

Personally, I don't like this FM6 way of numbering. In FM556, setting the document numbers "stuck." Because, in FM6 everytime you insert or remove a chapter file, you need to check and reset the numbering properties for the point of file removal or insertion on down the book file list. 

(In this reply, I do not address setting up the TOC ref page.)
