Hi NexusGod! Your little beardie looks so cute! Is your tank a 40 gallon "breeder tank"? Those are actually closer to 50 gallons and better suited for a fully grown bearded dragon. Some 40 gallon tanks can be too small. Also your photos show Fluker's Buffet Blend. I would only recommend live food for bearded dragons. Crickets sized to fit in the space between the beardie's eyes, dubia roaches and on occasion smaller hornworms.
Which
UVB bulb are you getting? Since you're setting up your enclosure for the first time, I'll link our heating and lighting buying guides.
Do Bearded Dragons Really Need Specialized Lights? While setting up proper lighting for your beardie’s habitat may seem like a daunting task, in reality, bearded dragons only need two types of bulbs—a
UVB bulb for mimicking the UVA/UVB radiation they get from the sun and a basking bulb for...

What type of bulb makes a good basking bulb? Why do I need one? A basking bulb is essential for keeping your bearded dragon warm and helping it regulate its body temperature. Basking helps beardies to digest their food and maintain their metabolism and immune system. Experienced bearded dragon...

As far as the bearded dragon hammock, I like this one
Amazon.com. It looks sturdier and with better suction cups. I don't think that a fully grown dragon would be able to use those climber vines since they are so narrow and bearded dragons don't really climb vines. They seem better suited for a chameleon. I would recommend sturdy, thicker driftwood instead.
The water conditioner looks ok. As far as vitamins/calcium, I like this Repashy product that is an all-in one. I've also heard good things about Zoo Med ReptiVite (although you will need a separate calcium supplement). Fluker's is probably also fine.. I'm just less familiar with it.
The Combometer looks good. I've also heard great things about the Zoo Med brand of a similar product.
Carolina Customs makes good light fixtures for your UVB. One consideration for this product is where you want your basking bulb positioned. Carolina Customs makes the same light fixture without the built-in basking. I think this may give you more flexibility. You'd also be more limited in the type of basking bulb that you could use since it requires a GU10 bulb. I see in your photos that you already have dome fixtures. I would use one of those for your basking bulb instead of doing the combo. I'm not sure what is currently in your second dome fixture, but hopefully it's not a coil UVB (those are no good at all).
I wouldn't recommend a forehead thermometer for measuring surface temperatures. An IR temp gun would be a more appropriate choice. Here's one option for you to consider that is pretty popular.

Good luck! Come back and post a photo of your enclosure once you have it set up.
