Help with sanding/priming bumpers

I decided to save a little dough with the paint shop and do the sanding of my WW RS sides and rear on my own (they came from other cars, so they are already painted the wrong color). Ive neevr done anything like this before, but its a good time to learn i guess. Can i get some advice on the preperation and which kinds of sand paper to get? And whether or not the “Primer-in-a-can” is worth anything at all. Any advice is appreciated. THANKS!!!

do a search on body work in the general discussion area… i think…
someone did a very nice detailed body work walk thru =)
