If you're looking for anatomy textbooks, then Moore's Clinically Oriented Anatomy and BRS' Gross Anatomy are comprehensive and sufficient.
If you're looking for an atlas, then Netter's has been a very helpful guide with excellent, clear illustrations.
I used Moore's but focused on the pictures and captions. If there were any gaps I'd consult the text itself. I didn't really like Netter's since a) the pictures are not as good, and b) there's no text at all to guide you. Reading through the text in Moore's is overkill.
