Well the current mods are doing a pretty good job anyway, but I'd defiantly try to focus on helping people, second chances, and Forum warning notices for pretty much everyone bar the most obvious trolls.
I'd also focus a lot on cleaning up several topics which are all to frequently found here, namely: religion, nationalism, and Vs threads.
I wouldn't ban them, just try to clean up the threads. In other words hand out short probations for behaviour which is all to commonly accepted (on all sides), like grouse generalizations and being an idiot.
