I had kind of the same thing going on in this thread: http://forums.adobe.com/thread/466960?tstart=0
I had to take the items I wanted repeated and put them into a subform, and put that subform into another subform. The first two outer subforms need to be flowed and set to allow page breaks. The most inner subform with all your content can be Positioned, with allow page breaks. Then I programmed a couple of buttons to allow me to add or remove the content.
