Display all the users points

Hi all:
on my site, i have two issues:
1. The users by points any show 1 page of users, so only the highest users are shown on that page. However we have lots of users and we want to see all their points
2. It doesnt not show their sumed points. I now have so many different categories so it is like this:
happydust valunteer work 100 points
tiana charity donation 70 points
happyudst charity donation 20 points

we want every user only have one row. and the points is the sum. can i do it now?

Thanks!!
