hi there this is a big task best of luck for the outside you must
rub down with wet or dry avialable at most diy if it is a short term paint job then you require any enamel paint this drys harder than normal gloss etc you will need a good quality mohair roller and a purdy brush try your local crown/dulux paint
warehouse they will advise
for the inside use vinyl wallpapers and low odour eggshell make sure this is oilbound
hope this helps
