Crab and Worm ID please?

[Dewman]

Well, yesterday I picked up some cured live rock a local store was practically giving away because they are halting their salt business and going only to fresh.
Anyway, I got several surprises withthe rock.
First, I got two Camel-back Shrimp. I threw them into my established 29. Then, I was moving the rock, and there was a big pinkish colored crab that looked EXACTLY like an emerald crab. Then, on one of the pieces of coral he gave me, there was a long worm like animal. it is highly segmented, and has a feathery head. I have seen bristle worms and it does NOT look like a bristle worm. It is grey and moves fast. it is maybe 3" long and has spent most of it's time clinging to one of my flowerpot corals.

Can anyone help out with ID? Thanks

Honestly, the crab looks JUST LIKE my emerald, except for the color. In fact, they were sitting together lastnight in my 29 (he escaped from the sump) and I was noting the similarities. His pincers are tipped with black.
I'm not worried about the worm, he doesn't seem to be causing any trouble and besides, I think my fish will eventually eat him.

I have looked in all the hitchiker directories and none of the pics look like my crab.

Need to post a pic if you can... It helps to identify it.
