Absolutely not. Bristle worms keep your tank clean of detritus, they don't hurt anything.
How old is your tank? What type of lighting? The FAQ I pointed you to will tell you white is always an unhealthy color for anemones, it means they're bleached. Mixing 2 types of anemones is not the greatest thing to do either.
The brown stuff is zooxanthallae, the algae within the anemone's tissues. They can expel it for various reasons. The FAQ probably tells you something about it. Have you read that link yet? It's quite informative.
