Looks like you've done research and got good advice here. Would like to point out that no matter if setting up frog in enclosure or a temporary hospital for quarantine and observation (recommended); strongly suggest you resist the urge of feeding frog for a couple of days. Once frog is settled in; then feed it late on day 2 or morning of 3 if day active species. An empty stomach is not affected by stress and the animal will use it's energies to deal with it; rather than for digestion.
