We use and like postmarkapp (http://postmarkapp.com http://postmarkapp.com) for their email API. You might also want to add Zend Framework (http://framework.zend.com/ http://framework.zend.com/) to your list of PHP frameworks. If you are looking into agile, I did some research and I personally like Pivotal Tracker (http://pivotaltracker http://pivotaltracker) for agile management, it makes implementing agile incredibly easy. LESS (http://lesscss.org/ http://lesscss.org/) is interesting if you have any interest in dynamic style sheets (also plays well with node.js if you go that route. Hope that adds to the discussion, I'm definately looking into some of the stuff on this doc.
