If you have a bunch of dead worms in there you want to get them out - they will only pollute the tank as they decompose. I know that we have said not to do any more water changes but if you have dead stuff in there then you are going to have to.
Another thing you might want to consider at this point is to remove your sandbed and go bare bottom - at least for a while. If you have dead bristleworms visible on your rock you can be sure that there are probably a lot more dead in your sand bed.
You want your tank stabilized before you add you fish back in. Maybe just run your canister filter on the bucket you have your fish in and throw a few pieces of live rock in there for filtration.
If it were my tank I would remove all inverts and corals to a bucket - mix up a fresh bucket of water - remove the rock and swish it around real good in this bucket of fresh water then siphon out the sand bed and probably most of the water. Then put most of the live rock back in and top off with more freshly mixed up water - test for a couple of days to make sure you don't get a cycle - then as long as your tests indicate it is OK add you livestock and corals back in.
