They are quite exhaustive already. In the history link I've done a bit but offcourse its a work in progress.
But if you want more, we need someone to volunteer the hours.
About a year ago, some members got on the case and did a great job - there's threads with their results starting here:

Compiled by Broncodroid and Bomber (with help from all captains)
Its an excellent list of stats. However, it was a lot of work and I recall Broncodroid and Bomber were pretty knackered by the end of it.
On the top scores thing. To my knowledge there are three players who have had a perfect score. Gorilla (Bluebags in 2003 I think), Bunny Boy (Souths 2003) and Legend (Bluebags in 2002 I think).
I'm pretty sure the highest team score would be as you said it. Parramatta have it for a F7s premiership match with 450.
