OH, the Will story is the big Nov. Sweeps story, so is going to be around for at least another month.
Bonnie has overstayed her welcome, so hopefully, she will be gone within the next couple weeks (it does seem from spoilers that may be the case)
As to Chloe...
In the past, Maggie has been the one that somehow got her nose and advice into others' affairs, however, I think perhaps this is just a way to keep Chloe occupied while the actress is pregnant. They cannot really give her much of a story, so it really is nice to see her interacting with so many different Days characters. What bugs me more is that since she seems to have settled in Salem again, why isn't Parker here as well. We don't have to see him, just know he is here.
I have liked that she is a good friend to Nicole, since NO ONE else is. It is hard for anyone to see friends in pain, sinking back down into alcoholism or drug abuse, unable to really do anything.
