Good!
In regards to your question about humidity, I've seen both answers get kicked around, and I think generally, either extreme is no good, so I would just keep it around normal range, which is high to begin with(55-65) and make sure the heat is up so the snake can fight the infection and dry out the infection. In McCurley's book he says that RI's are caused by a low ambient humidity(amongst other things) and so keeping it higher as opposed to lower is best.
