I've never kept roaches because I promised the family I wouldn't. If a roach got into the bioactive enclosure, would it dig itself into the substrate, or run around on it like my crickets do? You could also experiment with these 2 things for the roaches: a. see if they'll climb out of a...
Why is tong feeding a problem? Does that make you uncomfortable as well? I don't see any problem with letting them loose in the tank. Leopard geckos are supposed to hunt. It's extremely unusual for a cricket (I assume that's what you're thinking of) or a roach will cause your gecko problems...
Ideally you can get all shed out and even squeeze out the goo. If that's not making your gecko better it might be a good idea to consider a vet visit because maybe it will need antibiotics.

Is it really hot where you are? It could be hot. Otherwise I recommend keeping an eye on it to see if anything changes and if you continue to be concerned consider a vet visit.

Congrats on your new gecko! I started about 22 years ago with one gecko and went way overboard. Still have about 25 left, but we're all aging here now!

Are the hiding spots all on the ground? Are there any plants in the enclosure, even fake plants? Maybe you could post a picture of the enclosure.

I've owned a lot of geckos and some of them do seem to respond to human interaction. If your geckos seems OK with it and possibly initiates, I'd say go with it and don't worry about it. We may never know for sure but as long as it's thriving, it's OK in my opinion to assume the best.

The first picture does look kind of yucky. Is there a reptile vet anywhere near you? It might make sense to have an appointment and bring some poop samples.

Feel free to post poop pictures; it's not considered to be obscene. Sometimes my geckos' poop looks green as well. Sometimes when the poop is fresh, it looks green and when it dries up it's browner.
