In puppy class (yeah, I know it might be a bit different w/an older dog, but I think more similarities than differences), they taught us "Zen Puppy" lol. You mentioned you want to get her attention. Find a really great treat (small cubes of cheese, sliced up weiner, cubed chicken - has to be highly motivational). Standing there, every time she looks you in the eye (and you can coach her by making sound, whistling, or calling her name - although you said she doesn't know her name yet), give her a reward. It's to get the dog to look to you for guidance...like "I'm looking at you, what do you want me to do?" Anyhow, I hope your new dog works out; It sure sounds like you're willing to give it 100%
