I am a little bit stuck on what you have done in question 1. I think you might be misunderstanding how "localhost" works. It always means "the machine I am on now". Localhost on a server means "this server", localhost on your laptop means "this laptop", and so-on.
dbconfig.xml is a file that configures the Jira server's connection to its database. This might contain "localhost" if, and only if, the database server is on the same machine as the Jira server. The port is also probably wrong, most databases default to other ports, leaving 8080 for "web services". I have similar questions about the use of localhost in server.xml.
I think you'll need to put these files back the way you found them, as you say it worked before you started adding localhost to them. Then have a look at the reasons why you put localhost in them - what were you trying to do?
