I agree that the zombies were returning to where they felt most at home - consuming. So they most certainly represent that facet of avarice. But, if that's why they're like that, then why are the survivors surviving? Surely that means that they represent being outside of the consumer machine? And I'm not so sure about your take on Stephen, after all, isn't he just about the only one who still clings to hope? His obsession wth keeping the TV on in the hope that something might be broadcast to explain their predicament whilst the others have abandoned hope surely indicates his optimism if nothing else. He's about the only one with an optimistic view, actually. The rest act as if they're defeated already.
