I would only knock the plaster down if it is "puddling".
If the foundation is okay, you can widen the cracks and putty it up.
The wallpaper will hold up either way. Usually, the old putty is torn off, but you can prime and test glue one small area to see if the old putty holds.
If you need to paint, it's more reliable to put fiberglass fleece on it.
