Scott,
Borneman's book is great. It only really goes to the genus level of identification, occasionally diving into species classification. He covers everything from corallimorphs to stoneys.
Is a good book to id various corals down to the genus.
Even though it may not help you in sp. identification of many corals, it is a very very good book to read and have for some reference.
If you are looking for something that id's corals to the ID level, then your money is better spent on Veron's library, which I don't have, but I'm considering just for the pictures in it.
