One issue that might be important for you is the question of what morality means without a supernatural backing. In that light, I recommend What Would You Do Without Morality? and The Moral Void if you haven't already read them.

I've now concluded that morality has a perfectly normal meaning without any supernatural backing (and a meaning, moreover, which justifies trying to be moral), but it took me a while after leaving my religion to reach that conclusion– and in the meantime, it was a relief to realize that I simply wanted friends, family and even strangers to flourish and be well, even without a philosophical justification for that desire.
