Much as I respect him, as the "father of Paleo", Cordain's view on fat and salt is different from most of the Paleo community. He has supposed to haved changed his view on saturated fat, but I know that this isn't reflected in the latest edition of his book.
Most Paleoers think that he was kowtowing to the "mainstream" in not wanting to endorse sat fat. I think that he was scared that people would do "80% Paleo" and get themsleves into trouble by eating lots of fat without really dumping the carbs. If you eat a whole animal, you get lots of saturated fats. I suspect that animal fats (which are only partly saturated) are probably better for you than dairy fats (which are not really Paleo).
I don't have a view on salt, I don't think that there is strong evidence that links it to blood pressure, and I'm not someone that has ever put extra salt onto their food. I think that you're probably much better have natural "sea salts" than mass produced manufactured salts, but I've never really thought about it. It isn't one of the core Paleo prescriptions.
