Hey RedSonia, here's your answers:
1) This is a VERY easy change to make in Supremacy's editor. All of the minor races just have three generic shipyard structures, the Basic Shipyard, the Medium Shipyard, and the Advanced Shipyard (Only the Empires have their own specific shipyard structures and models), so all you need to do as click on the "One Per Empire" option in the editor for each of these structures.
So it's a change you can make yourself. Open up your Supremacy folder, and look for a file called "SupremacyEditor2.exe" and click it.
It can take up to a minute before the editor loads so don't click it again until you're
sure nothing is happening. Click on the buildings button at the top of the screen, then double-click on the structure you want to edit in the top-right list of buildings. Go to the scroll list at the bottom of the page that loads up, and scroll right to the bottom. The "One Per Empire" check box is there. Click it. Then close the editor and save your changes when the dialogue box appears.
I'm not sure if the minor race shipyards are implemented in your copy of the game though; i'm working on a major content update and I haven't got a clue what is and isn't included in the default game anymore. It doesn't hurt to begin experimenting with the game now though.
Here's a screenshot of the sort of thing you'll see when you load up the editor. It was too big to put in a post:

You will be able liberate any occupied systems (And get a huge morale boost and other bonuses for doing so, as well as a penalty from the race that was doing the occupying for obvious reasons) but if a minor wipes out a minor race then that minor race is wiped out. The end. You won't get a chance to contact the extinct race, nor will you get their bonuses if you colonised what remains of their system.
This is speculation on my part as we haven't discussed it yet and the AI hasn't been implemented, but i'm sure Mike will post here if he has other plans for the minors.
