A lot of what Dawkins has to say about morality that I want to comment on is in Chapter 7, so I’ll wait until I talk about that chapter to bring it up. Here’ he’s trying to claim that religion and morality are pretty much independent of one another, and to explain how a common sense of morality could have arisen if not from religion. He claims (p. 223) that people tend to agree on moral questions, even when they don’t agree on religion. (I wonder if that agreement about morality is the same sort of thing we’re talking about as “the Tao” over in the Abolition of Man discussion thread.)
There is ample evidence that atheists can be good, and that believers in God (and, probably, those who claim to follow any particular religion you’d care to name) can act evilly, so apparently Dawkins has refuted the claim (made occasionally by believers, and which has been discussed here on the SDMB though I don’t remember anyone strongly supporting it here) that you can’t be good without God. A key quote:
[QUOTE=Richard Dawkins]
If you agree that, in the absence of God, you would ‘commit robbery, rape, and murder’, you reveal yourself as an immoral person, ‘and we would be well advised to steer a wide course around you’. If, on the other hand, you admit that you would continue to be a good person even when not under divine surveillance, you have fatally undermined your claim that God is necessary for us to be good.

A couple of objections to this partially valid point.
First, one of the reasons I would continue to be good even if I stopped believing in God is out of habit. My conscience, inhibitions, moral sense, etc., which were formed in the context of my own religious beliefs and those of my family and my community, would not disappear along with the religious beliefs that engendered them. I have encountered the theory—and I don’t know how plausible it is—that, if religious belief were to die out, morality would decline, not overnight, but over the course of several generations, as the habits that society had learned die off.
Second, Dawkins’s examples of “being a good person” listed here involve avoiding evil rather than actively doing good. Does that make a difference? What about people who do good works from religious motivations? Personally, if I were on the fence about doing a particular good act, the idea that God would see it and be pleased by it, and possibly reward me somehow, and/or bless the act so that it would actually have its intended good effect, might be the extra motivation I need to push me over the edge into doing it.
And personally, my own notions of morality, of what I should and should not do, while not solely determined by my religious beliefs nor solely motivated by them, are closely enough entwined with them that it would be hard to isolate one from the other.
