Bless you for adopting this sweet girl in need. I second Marko's questions, I think daily walking and or strenuous play time for an hour would help her alot. Sounds like she is bored, and probably still anxious that something terrible could happen to her and her family again. Anxiety may be what is making her follow you constantly and lick. It actually may help to tire her out some and make her stay somewhere (like a yard) alone for half an hour(but maybe start with smaller increments like 5 minutes then 10). I also think obedience training would help you to bond with her in a way that may help her stress issues. If the nervous licking and such keeps up it may not hurt to consult a behaviourist, poor girl I'm sure is very very anxious. She's been through a lot in her life, it can't be easy.
