Yes, a vinegar or bleach mix can be used but like I stated, everything has to be rinsed extremely well and let air dry. Before you put any items back in, none of the items should smell like the cleaner.
For substrate I would use Plantation Soil, Zilla Jungle Mix, or a mix of coco fiber and peat. Since the Whites are aggressive eaters, try to stay away from substrates that tend to have bite size pieces of bark since your Whites will swallow them when they miss grabbing a cricket.
I would also have a drainage layer under the substrate and use a screen to separate the drainage layer from the substrate.
For some examples of drainage layers see some of the construction journals in the vivarium construction section of the forum.
The frogs you have listed should me housed in separate enclosures due to the toxins they secrete and the differences of how they move and eat.
Whites are aggressive and surely will cause stress with the other frogs.
As for water, your frogs will usually soak at night and water changes with Whites is usually needed daily since they dirty up the water quickly.
The Red Eye and Big Eye should be changed at least every other day and your Whites should not share the same water with the other frogs.
Daily misting should also occur for all these frogs at least twice a day and ensure keeping the humidity and temp levels appropriate to each species of frog. See the care sheets located at the left of the forum for more info on each frogs requirements.
Hope this helps
