They are beneficial and they will not harm healthy, living tissue. The only exception I've seen is with H. zostrae - dwarf seahorses.
If an organism is dead or dying, or there is extra/uneaten food, they will be all over it like stink.
You want them to do that - you don't want waste rotting away in the bottom of the tank - you want something to eat it.
If you got "bristled" - soak your hand in vinegar - that will melt the spicules away. You can also remove them by sticking duct tape on them and ripping it off but I've found that causes more pain than it cures - vinegar works fine and less traumatic.
If you have "too many" bristleworms, it's quite likely that you are feeding too much - they respond to the food supply. Cut back on the food, the worm population will decrease.
Some wrasses and orchid dottybacks will eat them too.
