Sean Carroll, who will soon be debating with William Lane Craig, I believe, some time ago organised a conference of sorts with some big name hitters in the naturalism world. I strongly advise watching these, though you might need to concentrate in parts. The most fascinating ones, in my opinion, are the ones on free will and consciousness.
Here is the info given on You Tube for the videos / workshop:
