As for being skitish of other animals, its possible that without his doggie friend he is having some anxiety...be there for him and show him that it is ok, be patient and hopefully he will come around.
AS for the barking, My pup barks at the doorbell. I am not sure how to get her to stop, I am trying right now getting her used to the noise even when nothing happens. so we have a fake door bell noise on the computer and play it now and then....it is starting to work.
