Preprint on CV - should I include journal I submitted to?
No, do not list the journal you submitted it to.  Frankly, it means nothing: anyone can submit anything to any journal.

Of course, you want to your CV to accurately reflect how much work you've been doing lately, but there's always a chance that the paper gets rejected in the in-between phase.  A good enough compromise is to just post the arXiv info, when it was revised (this reflects that it's been recently reviewed), and perhaps "Accepted."  Once you get the proofs, you can change to "To appear in [Journal]."
