If you want a good book to get on the F-4, I would suggest
this one. There is a newer version of it out that is a bit more comprehensive, but it is probably the most authoratative book on the Phantom I have seen. It covers all the variants.
As far as the "Walkaround" and "In Action" books, as far as I know, they are out of print. The best place to look for them might be a hobby shop.
