Thanks for that.
Bless her, she sounds like she's been through quite a bit.
I think this a very confused soul who doesn't know if she's coming or going or when that is going to be!
I would suggest that some confidence building is what this dog needs, both in herself and in you. She is showing deference but is so unsure what to do or what is happening next.
Go gently and use the reward only system at first. I think that teaching her some basics pretty quickly is the way to go. Even if she already knows the commands the object is to teach her how to accept the reward process and take that in her stride too.
Start with the sit on the lead, when she obeys give her very quiet, calm verbal praise, "Good girl" will be enough. Give her a treat and remove your hand once it is accepted. Walk a few paces and sit again. If she is doing this well try it off the lead. If she does this well add the stay, using a hand signal as well (your hand up, palm towards her) and move two steps back from her, wait for two seconds and go back to her. Give the same praise as before. Do this with the down too. No physical praise until she is calm and sure of what is going to happen and what is expected.

In the house teach her to lie on her bed following the same method. Never give her any physical praise if she asks for it - she must understand that this is up to you and she is not welcome all the time. It's also important that she knows that she's fine and can cope with life without being stuck to your leg! When she has been lying on her bed for a few minutes go to her and give a treat and calm verbal praise, then bend down and stroke her gently on the head. As soon as tries to lick - move away from her. She'll get the message and will feel happier and more secure once she understands the rules.
She sounds like the kind of dog that, once you have built a relationship with her, will be fantastic to train as she will be very willing to please.

I hope this helps, please let us know how you get on with her. Good luck.
