Another credit card question

Another credit card question

How much available credit should I have? I think I have entirely too much (about $20K), but I don't want to lower my credit score by closing accounts. And since I have a high credit score, my limits have all been bumped up recently. I've got four credit cards, but only use one of them (for frequent flyer miles). How big a dip will my credit score take if I only leave one card open?
