As the veteran of many, the biggest bit of advice I can offer is know who the intended audience is, and write to it, especially if you’re not the end user of the document.

Information or data that you think is important from your own perspective, may easily be flicked away with a stroke of the red pen (followed by the word ‘resubmit’).

If writing a PAR, or indeed any document, for someone else, it’s vital to get inside their head, writing it as if they were doing it themselves. It’s also a central tenet of managing ‘up’… you hit on a lot of good points previously under ‘Influencing Others’.
