For that last question, yes, your baby will lose the banding and gain spots. It's very cool to see and compare pics!The yellow can turn various shades during this process.
When he does open his eyes finally, is it cloudy looking or clear? Are the eyelids crusty? I have a gecko rescue that has spent a lot of time at the vet for his on-and-off eye issues, part of it was that the shed from the eyelid had gotten stuck in his eye. My vet says he is also not cleaning/licking his eyes like he should be, so his eyes are cloudy. Antibiotic cream under the eyelid didn't help him, but it was the first course of action my vet took, and maybe it might work for yours? My vet said there's not much we can do if he isn't cleaning his eyes except to clean his eyes for him when he needs it, which a good vet could probably teach you how to do.
She looks like she needs a couple grams, but as you say he appetite is strong, so that's good. I'm sure her eye issues would hinder her ability to hunt, as that was the case with mine. Try free-feeing her mealworms in a dish, as they are easier to catch and she'd be able spend the time to poke her nose around and feel around for her food without the food running away.
