The general consensus here is that FA alone is enough for pharm, and that it's probably the only source you need. I keep hearing this over and over so there must be some truth to it.
Also, I used Pharm Recall for some sections to clarify concepts. That book actually has more information than it looks to have. A few drugs in there are obscure and probably a waste of time, but if you use it in conjunction with FA you should be golden.
Good luck.
