Earwigs are dark colored, silverfish are...silver. Earwigs mostly eat dead stuff, but they may go after live plant tissue. http://en.wikipedia.org/wiki/Earwig
Earwigs in your compost = good
Earwigs in your vegetable bed = probably nothing but could be trouble
If you put unfinished compost on your beds you will get a bunch of them. I have never personally had a problem with them, but then again I have never had what I would classify as an infestation in any of my growing beds.
