The reason your tank was infested was because you were overfeeding.One of my tanks was pretty infested with them. They normally hide in or under the rocks. I was able to get a lot of them out by just lifting up one of the rocks, since they were all just sitting there. I sucked them up with a coral feeder. I also heard that you can use soda water on the rocks to get them out (I never tried this though).
No you don't. It won't hurt anything. People spend all sorts of money for "clean up crews" and then throw away valuable members that they got for free. These are nothing more than relatives of the earth worm with some spines for protection.I gotta get him outta there.

Common bristle worms won't hurt anything that's healthy.
Feather starfish? They don't live in closed systems.
