Hi,
The master page for the buttons should not be a problem and does make life a little easier ( although another alternative is fragments), but as this works I wouldn't worry about them.
To make your new sections start on a new page you need to select the subform you want to start on a new page and
Goto the "Pagination" tab
in the "after" drop down select "Go To Next Content Area" or "Go To Next Page"
and just play around with these until you get the look you want
regards
Malcolm
