Using PMD and FindBugs in TeamCity

Normally I just use IDEAs code inspections and use the duplicates finder in TeamCity.
However, a recent client has requested that the code that is delivered is checked with a FindBugs and PMD profile.
I've not used these before and I'd like some advice.
Is there an easy way to integrate them with TeamCity?

• Do I have to write a build script to run them and use an Ant Runner or are there runners that can just point directly at the xml configs?
  
• Can I make the build fail or send out an email if the metric in the reports goes up?
  

Are there common configs for each of these tools or do I have to configure them from scratch?
