First forget everything you know about deer hunting

well.. sort of. Things you need before going afield: 1: Read the DNR handbook on predator hunting and night hunting.
2: gun:, does not matter much, but something larger than a 22lr. Lot's of guys use shotguns and lots use rifles, Depends on your hunting area. Coyotes in Michigan run very fast and normally wont stop when coming to a call, if you use a rifle you have to be a good shot. Shotgun with #4 buck durring the day and a heavy turkey load is the norm at night. I also hunt in some what populated areas so i use a shotgun 85% of the time.
3: camo: hunters orange is required durring the day, just like deer hunting.
4:Calls: there are a wide variety of calls out there. If you only buy one call, get an open reed howler, you can make prey sounds with them as well as howl. You will develop a liking for certain types of calls after time.
As far as land go's your best bet is to hunt farmland and thick cover that holds prey animals like rabbits. Good rabbit land should also be good coyote land. knock on a few doors or ask friends if they know anyone with a farm. Or find some public land and scout for tracks, Coyotes live about everywhere.
Also know that coyotes like to circle downwind and smell the source of the sound, so be aware of this and how you set-up. I like to set up in a cross-wind.
Sit at each spot for about 30min, then move on a 1/2 mile or so.
hope this gets you at least started a little, there are a lot of guys here that know a lot about coyotes, so stick around and ask as many questions as you want.
good luck.
