Hello, welcome to the forum, you and those two!
They look very adorable, healthy and beautiful! I also think they have a very good setup over all, but there is a few things that I will reccomend!
Hides are very important to a gecko's wellbeing, although I would suggest a few more. Each gecko should have access to any hide at any time, meaning there needs to be a hide available for each gecko in each temperature gradient for equal opportunity. Generally, it is 3 hides per gecko, I would at least add another cold and humid hide, seeing as the warm hide is big enough for both. Another thing you probably want to do is move the humid hide to the warm side to prevent respiratory issues.
Calcium dishes are not usually needed if you are supplimenting correctly. It can actually lead to an over dose in calcium, I would only reccomend it to geckos suffering from MBD or breeding females. May I ask what you suppliment with and how often?
Substrate is a huge debatable topic and it is up to the keeper! I personally think it is okay to use loose substrate if you are alright with the possibilities of your gecko eating it (Not necessarily meaning they will get impacted) or getting it in their eyes, etc. If all their husbandry is correct then I see no problem with Eco Earth. Repti-Carpet seems to harbor bacteria and gecko's teeth and claws get stuck in it, I like tile or sand mats the best for easy cleaning, but Eco Earth is the third favorite for me!
Thermostats are used to control temperatures of your Under Tank Heat mat, I didn't see you list it, it is very important to have in order for your geckos to have appropriate temps and better digest their food.

Here's a temperature guide for all leopard geckos as measured with the probe of a digital thermometer (and controlled by a thermostat):
•88-92 F (31.1-33.3 C)
ground temperature right underneath a leo's warm dry hide
•no greater than 82ish F (27.8ish C)
air temperature - 4 inches above ground on the warm end
•no greater than 75 F (23.9 C)
air temperature - 4 inches above ground on the cool end
Gender is very important to know, how old are these guys? Only females can be housed together unless you want to breed. Understand that by housing them together you risk fights but it is possible
IF they are females. If they are anything but females, you will have to buy an entire new setup so be prepared.
•Sexing Leopard Geckos Leopard geckos become sexable at about 6 months old. Males can be distinguished from females by a distinct v-shaped row of pores and by bulges right under the vent.

Good luck with the cuties!
