Hi John! Make sure you use a wallpaper sizing/primer first. It gives the paper a better surface to adhere to. Also, it'll make it much easier to remove the paper down the road so the wall underneath won't be damaged. They also sell this in home improvement stores: https://www.amazon.com/dp/B000BQS1C2/ref=psdc_13399671_t1_B000BQM1NC
Hi john. Should be able to just paste the wall or the paper and just apply.
I would prime the walls first. Then the paper will be easier to remove when the time comes to do so.
