OK rereading your OP multiple times, the first thing you need to get settled is the database export / import. You need to get the settings and passwords into your new system. Without the database the rest of the bits are pointless.
If you are running fog 1.2.0 or a trunk release then there is a built in function to export the configuration from within the gui and then import into your new server. There is no need to use the spiceworks method. That is for the 0.3.x and older release.
GO into the Fog Configuration and select the Configuration Save option that will download the fog_backup.sql to your computer, then go to the new server and upload the settings.
