Happy to help Np.
The fogger isn't really necessary. You want humidity as if they were out in the woods in the summer, a summer when it rains each day a little but not like a rainforest. The reason over humidifying is potentially harmful is that it promotes the growth of molds and fungi, some of which aren't visible to the eye but are potentially life-threatening to Gray Tree Frogs. The other reason over humidifying can be a problem is that in order to maintain the sticky, tacky quality these frogs need to climb and which is a primary indicator of overall good health, they need to be drier than other species of frogs and they don't dessicate like any aquatic frog will if it's out of water for even a relatively short time. Along with the molds and fungi, and the increased bacterial growth that comes with higher humidity, use of a fogger or over-misting will make it necessary to deep clean their tank far more frequently. For these reasons I recommend against a fogger.

The most important thing you need for humidity in a Gray Tree Frog habitat is a good sized bowl of water just deep enough for the frog to sit in without floating so it covers about half way up their back. This alone will keep good enough humidity along with a daily misting and it's also how they drink and expel waste water. If you take the time to watch your frog while he sits in the bowl you'll notice him flinching as he sits, this is him expelling waste water and as he does this he takes in the fresher water around his body. Sometimes they'll take a little in through their mouths by holding their lower jaw a little open right at the water level.
The fact that they're also expelling waste water as they sit in the water makes it necessary to change the water daily when they're using it daily. During the inactive months they'll use it far less but they still need it and whenever you see that he's in it you should change it once he leaves it so its fresh for the next time he comes down to soak.

As for feeding, hand/tong feeding is fine but don't be worried if he's not interested much during the winter months, he doesn't need to eat very much at all.
After he's soaked in the water bowl until he's had his fill he'll be very fat, almost bloated looking, and ready for a few days of good sleep. The best time to offer him food is at these times, after he's soaked but before he's gone back to sleep.
