No, which is included in the installation 'package.'
Yes but they need to come from some where. The example I was trying to raise is that you haul TN material to a barren world (barren in the sense that there are neither TN nor classic resources present) and use for example engineers to build something.
Where does these other non-TN materials come from? Nowhere, they just "magically" appear.
IMO non-TN minerals extraction and movement could also abstracted into increasing the size TN minerals take in the cargo holds, at least so minerals and end product require the same size of cargo hold to haul.
