Also, .22lr is a perfect caliber and power for varmints and unobtrusive plinking. Use hollow points for animals and solid core for plinking. While .22lr can kill something as large as a deer (illegal to do), only with a head shot, it is better to use .22wmr for larger non-combatant animals like coyotes. It will depend on the regulations in your area too, since that is also a rimfire cartridge. Regs may only allow centerfire cartridges for some animals. For scaring off people, it doesn't matter what caliber you use, people generally don't like getting shot and readily avoid it. For combatant animals like big cats, hogs, bears, etc, you'll need something more if you don't have a good can of spray with you. The best part about .22lr is the amount of ammo you can bring along without adding much weight. Same goes for .22wmr, but it is a lot more noisy.
As far as pistols and revolvers go. They are okay when you are doing something else, but want to have something to shoot with when you cross paths with something else. They don't get in your way while working and such. For dedicated animal shooting and plinking I prefer a rifle. They are heavier and bulky, but they make up for it in accuracy and being quieter. They also have better muzzle velocity though that depends on the individual firearm most of the time. If I have to choose between a pistol and a revolver, I'd go with a pistol since it can carry more rounds. Unless you have custom sights, both won't be as accurate as I like and I'd need a lot more practice with both to feel more competent. Because of that, I'd want more rounds to fire between reloading. compare that to the single-shot, break down, .22short-.22lr rifle I use now for varmints. I've never missed a single shot with it even though it has shitty pistol style sights.
