Thanks! I've always had a habit of taking it slow...sometimes way too slow I feel. So now I think I need to speed the project up a little...LOL
Dart frogs are said to be nontoxic in captivity...or at least they are not as toxic as they are in the wild. That doesn't give you an excuse to stick the rubbery little things in your mouth though! In the wild of the many species only 3 species are used by the Indians for hunting(Phyllobates terribilis is one). One site says the wild ones are so toxic that a chicken can die just by pecking a paper the frog has walked over

...but in captivity they are no worse than any other dart. I appreciate your caution and consideration for fellow family members in this regard though! If I was in your place I would be a bit uneasy too.
The red legged walking frog is a totally different frog, across the pond in Africa. I think they are probably some kind of true frog. Sci name Kassina maculata.
If your mystery frog is a leopard frog like I think it may be you could do a pretty cool pond habitat using some of these guys. I can see some plump leopard frogs watching you from under some ferns at the ponds edge...(maybe its because they are not wild here but I think leopard frogs are very pretty frogs). I bet leopard frogs would be pretty amusing captives...feeding time would probably be a blast! You'd probably want a pretty decent sized water section. No idea how tall a 75 gallon is but since leopard frogs tend to stay close to the ground you will not make much use of your vertical space. I'd bet in this case a few small fish would be fine in the pond with the frogs, but might dissapear every once in a while.
Never heard much about glassfrogs in captivity...so I'm assuming they are very rare in captivity. A few reed frogs(Hyperolius) look similar though, but those are all WC.
Have you heard of the vietnamese mossy frog(Theloderma corticale)? Now that is one cool looking frog...supposedly easy and easy to breed. Quite a few plants from Vietnam are available so you could try a sort of biotope...the frogs are said to naturally live in small limestone caves and along streams. Sorta an aquatic treefrog...they can climb well but adults love water.
I'm planning on lots of different plants, trying to stay with South American ones.
www.cloudjungle.com stocks alot of cool plants some of which I'm thinking of. Bromeliads, Peperomia, moss fern, you get the drift

The tank will be done using the false bottom method...(piece of plastic screening type material(eggcrate) with PVC supports to hold it up and provide a place for the water to drain to) so I will just cut a section of it out for the pond. It is hard to explain so I will post photos soon.
This is cool as you and I are more or less at the same stage of this little experiment. Bring more stuff to the table!
