Jumping in on this; I’ve found jurafsky/martin a good place to start. Covers a lot of ground and is a pretty good read as well.

As a somewhat established researcher in the field, I second Jurasky and Martin. It is peerless and what I recommend to anyone joining my team if they think their background NLP knowledge is a bit on the weak side.
