The first of these is that I want to be able to use over-layed text /

customer order confirmations, once the customer confirms they have

If FOP supports block-container you can use an absolutely-positioned
block container to overlay the text. If you want it to be diagonal, you
will need to use a graphic for the text (easy to do with EPS or SVG).
The one limitation may be support for Z-order--if your FO implementation
doesn't support Z-order or doesn't default to the behavior you want you
may not be able to force the text to overlay the region-body content.
Z-order is the property that determines the vertical stacking over
overlapping areas--a higher Z-order value should be rendered above (on
top of) areas with lower Z-orders.
Since the overlay would need to be static content (so it could apply to
each page) you'd have to put in into one of the edge regions with the
region's extent set so that it overlaps the region-body. Different FO
implementations may vary in how they place the areas involved, so it
will require some testing to determine if what you want will work with a
This problem can also be addressed using a PDF post-process using a
tool. Adding an overlay to every page of a PDF is a pretty simple
operation. See www.pdfzone.com or www.planetpdf.com for a list of likely
