I saw some of these set up at the Arizona Frog Day, and they seem very nice and practical. I would skip the fogger, especially if you plan to use one of those little ultra-sonic things. They don't work well, and poop out in no time, and can actually be dangerous to the frogs, from what I understand. Fog looks interesting for awhile, but you don't really need it. Hand misting is easy, and often if you have a waterfall and water way with a false bottom, you sometimes don't even have to mist very often, depending upon your set up. I have found that the little 40 oz. pump misters are more practical and efficient than the larger garden sprayers. I prefer to use the RL Home and garden sprayer, 2.5 pts. You really won't have to have a humidifier with a closed tank and water features. If you do, there is a nice cheap one that works off an aquarium pump, bubbles water through a container and delivers it through a wand. It's called Tropic-Aire, and can be purchased from PetCo or other pet stores for about $15.00.
