The only advice I would give is to spend as much time as you can desensitising her to other dogs. I would find something of value to her (a ball, Frisbee, food) and train her to focus on you using the high value item as a reward, once you are confident with her response to your focus command, start taking her on walks, however keep a fair bit of distance between you and other dogs, even if you have to cross the road and command her to focus (rewarding her with your value item once she does). Give her space and time to gain confidence and learn how to behave properly. Try to set her up with situations where she will have more success' than failures. Eventually you may be able to reduce the distance between her and another dog so that you can pass by. I wouldn't bother with allowing her to meet and greet strange dogs - she doesn't need to do this, she does need to learn to ignore them.
With the lunching at people, I would start walking her with a head halter type device such as a 'canny collar' and also a check chain (click both the canny collar and check chain onto the lead - this is for safety if the head halter comes off for some reason then the check chain will click into action). Using a head halter will help you control her head much easier than a flat or check collar and will allow you to easily control any attempts at lunching whilst you train her out of lunging. Once she has unlearned this behaviour, and you are confident with your handling ability, you can ditch the head halter and choose a collar you are most comfortable with.
