Rio - Stay away from Barra. It's the suburbs and you don't want to go there. The BW seems to be in a great location.
Iguaçu - don't forget to visit Itaipú. Do the technical tour - you get to go inside the dam and see how the power plant operates. It's a 30 min local bus ride away from the city (same distance as the airport, but in the opposite direction). You should pre-book the tour.
