I've used a non camo shotgun since 1994 and have had turkeys within 10 feet of me, with no problem, and I sneak in close getting a nice gobbler almost every year.
Videos, cant think of any good ones right now.
Locating Turkeys.....Reaserch on the web first I.E. turkeys in elpaso county, canyons, trails etc. ask friends, game wardens etc. then look at a map of the area locate creeks,tanks etc. then find the south or east facing hills,mtns, or gullies with roost able trees. Thats your starting point.
My best teacher was the hunt. If they don't come your way just wait and learn their habits, in my opinion knowing their habits is your best edge.
