- linking the wormholes randomly so they go and change each game
Well, you can set a chance for phase lanes, which includes wormholes, appear. However, there is no way to do it so that each wormhole is guaranteed to go to a set of other wormholes. So you could get wormholes that go no where or one way wormholes.
- making sure the planets at the pirate planets ALWAYS get to have a weapons relic on them
That's extremely basic in Galaxy Forge, edit the pirate base, go make a new group, find the weapon artifact item at the bottom, set to NoOwner and Always.

Edit -> Players from the top menu. Also make sure to set a planet for them to own and be a homeworld.
- making sure that the players start on there correct home world
Set RandomizePositions to False.
