The first thing that jumps out at me is that you minion is connecting to 4505 but your master is failing to start because something is already bound to port 4506.  Are you truing to run on 4505 of 4605?  Any reason why you aren't using the default ports?  

[Phipps, Thomas]

4505 and 4506 are the default ports. I would say stop using the port settings. If you are going to use default settings just don't set them.

since the logs look like standard out logs I'm willing to bet the user tried running the salt-master by hand while the system daemon was already running. which would give the output.

As for the original question, check for firewalls, on the minion, master, and in the network between them. stop using options that are set to defaults, only add settings if you mean to actually change away from default.
