Nicer looking pdf output from docengine

There's a few css styles that makes the docengine HTML output look good, that doesn't quite cut it in the PDF output.
Attached is two screenshots with comments.

1) Remove navigation bar at top. This one does not have any effect in the PDF output.
2) Remove borders on each side. These are borders between the white content and grey surroundings in the HTML version.
3) No page break before first h1, only the subsequent ones.
4) Remove the grey background at the bottom and top. Looks great on HTML output with grey on all four sides, but not on PDF output with grey only at top and bottom.
