Regarding page sequences, any block element with the CSS rule
-fs-page-sequence: start
will start a new page numbering sequence.

Regarding (2), counter(pages) is always relative to the current page
sequence, but maybe you can accomplish what you want with running
elements and a custom initial page number in ITextRenderer. It would
be relatively straightforward to add a custom counter(-fs-total-pages)
counter too. If you do work up a patch for that, it will definitely
be applied.
