I did my second read immediately following my first. It was better than the first (except for a few plot surprises) and none of my other subsequent reads have been so revealing. The prophecies and religious stuff was really something I glossed over on the first read. Plus, Robert's rebellion and the Tourney at Harrenhal were far too confusing the first time. Oh, and that's the same Lord Wyman Manderley in A Dance with Dragons as in A Clash of Kings.
