Put the frame of brood and nurse bees in from day one. The nurse bees will cover the brood (keep them warm and fed). Just be sure there are some eggs in the comb, this is what they will make an emergency queen out of. The bees from the trap out will be foragers bringing in pollen and nector, since they can not return to their original hive they will start living in the trap out box. The foragers are in "forage mode" and all they want to do is bring in pollen and nector. Be sure to check on the trap out hive daily to be sure it is not completely full, it will surprise you at how fast it will fill up.
Just remember you need eggs!
Good luck and keep us posted!
