Jason, The general run of thumb with IDS is the closer it is to the system you want to protect the more effective it is. If you deploy outside the firewall you will be learning about attacks being launched against your site. If you deploy inside you'll be learning about the attacks that have been successful at reaching the machine you're trying to protect.
