Yeah, you don't need a dictionary. (the internet! I was issued Stedman's at the begining of the year and haven't opened it. I don't forsee a situation in the future where I will open it)
As for atlases Netter's is the gold standard. (not sure why it wasn't on your list) Rohen's is good for quizzing yourself before an exam but I personally wouldn't want it as my primary atlas. I have heard some good things about the Thieme atlas (Gilroy) so if you have to go with one of the ones on the list go with that one. (I have a family member that teaches anatomy and she says Thieme is a good atlas) I have never heard of the Moses atlas, had to look it up. Seems to be another picture atlas. Again would not recommend as your primary atlas. (but great to supplement)
In regards to the IM books, sorry can't help you.
