Just to add to what Wormwood has already told you, unless you are able to put the toads through a seasonal photoperiod and temperature reduction over a number of months, breeding these toads will be next to impossible. Few people breed them successfully, or any temperate frog/toad/salamander for that matter.
Bufo americanus habitat is quite varied. They're a hardy toad, but I would say you should think of deciduous woodland as being the main habitat for adult toads. As for breeding habitat, they will breed in almost any water body available in the spring, from very shallow drainage ditches (we're talking a cm or 2 of water max) to deep ponds.
