Use my summary!
No, seriously, if i have to think about one thing to take from the summary that will be... wow, thats hard...
but i think negotions will be in order. I have a full section detailing how you can negotiate anything like:
You ask for 500 credit.
Side B says: only if you give me laser tech.
You answer: i can't give you laser, how about genetic engineering instead?
Side B replays: fine, but i only give you 400 credits then.
You replay: give me 600, and i'll add two missile friagetes.
Side B accept.
