I'm am older hunter and still read books, there are some good coyote hunting books, Ron Spomer, Gerry Blair and Phil Simonski all good reading to learn about coyote hunting.
Most of the videos I've seen were just "kill shows" with little instruction, but there is a pretty good one from Tony Tebbe of Predator University.
Most public land in WA will have coyotes, finding sign, tracks and scat is a big plus.
Learn to approach your stand unheard, unseen and unsmelt.
Use the wind to your advantage you don't want it to blow your scent into the area you think the coyote will come from. A coyotes nose is very good, cover scents don't work, to them you just smell like a hunter with cover scent on.
On the stand don't skyline yourself, try to have some type of cover behind you to break up you shape, sit in the shade and keep movement to an absolute minimum.
As to sounds, there is no magic sound most will call coyotes if it peaks their interest, even sounds of animals that they have never seen or heard before. If using a mouth call the more emotion you can put into seem to trigger a reaction better.
Shoot straight, practice shooting sitting as you would be on your stand.
Enjoy yourself and don't get discouraged it is tougher than it looks on TV.
