Wallpaper can be reglued using the following method ( works for me):
Use a damp rag, and a heat gun set on low heat. Heat the paper and then wipe with the wet rag. The hard part is knowing how much to heat the paper. Too little and the glue won't re activate, too much and the paper will curl.
Start easy with the heat gun, you can always add a little more. As for the paper on the cabinet, use some good wood glue and apply with a cheap hobby brush.
