Rob, Try Edgar Puryear's _American Admiralship: The Moral Imperatives of Naval Command_, published (of course) by Naval Institute Press---it is more hagiographic than Ricks' Generals and is based on a series of oral history interviews.
Self promotion alert, my chapter for the upcoming Cambridge anthology (eds. Murray and Mansoor) will include a post-WWII chapter on Navy culture, but it looks at several important admirals --Zumwalt, Rickover, Turner.
