I'd recommend taking an intensive ESL course, which you presumably have many options for at local universities. (My wife, who is Japanese, is similarly looking into options.) If that isn't an option: For listening comprehension, and eventually speaking, practice "shadowing." Have her listen to interest-appropriate TV shows and say exactly what the speaker is saying, in real time. (You can also do this exercise with transcription.) It will be maddeningly difficult at first, but with literally hours a day of doing it, she will see radical gains. This is a large part of the training for professional translators/interpreters. In my experience it works very well. It is also some of the most frustrating work I've ever done.
