This is not Postfix specific, but I think worthy of investigation.

This is what needs to be edited.  IIRC, there are options when you install 
Postfix.  This may affect how this gets set.  I think if you'd just changed 
this and perhaps /etc/mailname you'd have been fine.  From a Postfix 
perspective, I don't think the hosts/hostname changes affect things.

That is AFAIK the way it is supposed to be.  Hostname is the name of the 
machine and not the FQDN.

Yes.  I think this is worth investigating.

I think your /etc/hosts issue is independent of your Postfix issue.
