Like you I have an interest in document preparation but couldn't find any 
definitive source to learn how to do the more advanced things in 
Mathematica. I eventually concluded that I had to learn how to create 
stylesheets myself. I have learnt how to do this by looking at the supplied 
stylesheets using Format | Edit Style Sheet | Import Private Copy, and then 
Format | Show Expression to see exactly how their cells work. If you poke 
around like this then the general rules for how style sheets work gradually 
become clear, and you can experiment by making changes (by toggling Format | 
Show Expression and editing carefully) to see their effect. Remember to use 
Import Private Copy otherwise you will be editing the master copy of the 
stylesheet, which you probably don't want to do.

Anyway, the key words you want to look for to control the way that cells 
group together are "TitleGrouping", "SectionGrouping", etc (for the Default 
stylesheet). You can find these by doing Format | Show Expression on the 
whole of a stylesheet, and then searching for the strings you are interested 
in.
