Wow.........where do I start haha? Probably the best way to begin would be to tell you that you are doing fine. Everything sounds good, even the foliage he's hanging on looks perfect. Just wanted to clear that up as it seems you've been bombarded with some information that might steer you to think otherwise. He looks good to me, and if you are nervous that he may be dehydrated just check his urate. If it's white or close to white, he has plenty of water. If it's orange or yellowish, you can offer more water. If you have a misting system there is no need to add a dripper. You can if you want, but it'll probably just end up being more water to clean up. Usually you only combine the two when you have a WC animal or a montane that would require pretty consistent watering; veileds are easy in that they require much less when watering. The misting schedule you posted without the dripper should be enough for the day, but if not you can always adjust accordingly.
The superworm thing is a complete load. I've fed them out numerous times without ever having problems. It is 100% a myth. In fact, the only way I can see something like that happening is if the animal ingesting the worm is seconds from death. All my animals thoroughly chew their food to mush before swallowing. With that said, I see no reason to exclude superworms completely from his diet. The only reason (which brings me to my next subject) would be if he's refusing other food items (which it sounds like he is haha). If he's really liking the worms and won't eat crickets/dubia you can try starving him a couple days or more, then try throwing him some crickets. My male panther is a turd about this; I can't give him much aside from crickets because he LOVES worms. He loves them so much that if I give him one or two, he WILL refuse his crickets for around a week. When I say refuse I mean he'll let them roam the cage til he realizes I'm not coming back with a worm, so eventually he gives in and eats them. He's like a little kid who won't eat his vegetables haha, so he doesn't get to eat anything unless he eats what's in front of him.

And as far as lighting goes, you are correct. Twelve hours on, twelve hours off, that's all you need. If you WANT to drive yourself crazy you can set it to outside hours haha, but that's getting a little extreme.
Hope I cleared some things up a bit, but don't worry yourself too much as you seem to be doing just fine. In fact, you seem to have done your homework from what you've been replying with to the other posters. Any more questions and I'd be happy to help but again, TRUST YOURSELF!! haha
