Able 2 know mod & Updating Phpbb

I have a couple questons. What is the easiest way to update a heavly modded board for security purpose?

Also I am getting many of those urls indexed using the able2know mod.
www.mydomainforum/posting.php?mode=quote&p=210

I thought the robots.txt was suppose to fix this issue?


My robots.txt looks like this:
