You'll need several small fish safe swimming pools to rear the tadpoles and a lot of blackworms (as the tads are carniverous)... and a lot of pvc pieces to keep the tads and metamorpsh seperate, a filter for the pools...

Get a copy of Horned Frogs (General Care and Maintenance of Series) (General Cake and Maintenance of Series) (Paperback)
by De Vosjoli (should be about $6.00 on Amazon.com) as it describes the process pretty well..
