I have 3 problems here.
1-I can't seem to be able to attach the Extras addons to any of my ship designs. I click them but the place button never activates.
2-I'm can't seem to grasp the concepts between my work forces. I notice sometimes when I'm researching I have income, then I go to social or military and all the sudden I'm losing a lot of money. I guess I'm having a hard time designating a balance between factories and research facilites and possibly banking. Any help in understanding the balanse would be cool.
3-I research Starbase abilities. I build my constructors to build say a military starbase, yet the base is still without any attributes. Are these attributes I've researched simply adding weapons and shield typs to the constructor I will be using to build the starbase? I haven't tried that theory yet, but according to the info I see from the research, it seems differant than say, a specific weapon type or shield type.
Appreciate any help you all can give, Thanks.
#1 - I think placing extras is a little different to placing normal components. To place an extra, you click on the extra you want and then click a 'hardpoint' (the little red dots) on the ship picutre to place the extra on that point.
#2 - I don't fully understand either, but I'll give it a go since nobody else has replied.

As far as I know, factories and labs create points. If you're operating at 100% manufacturing capacity, each of these points will cost you 1bc from your treasury.
For example, you have a factory that creates 4 manufacturing points per turn and you are running at 100% manufacturing capacity with all your focus on social production. Each turn, 4 bc will be deducted from your treasury and it will translate into those 4 MPs which you use as social production.
I think in the latest versions of the game, any spare social production is assigned to military and if no ships are being built, the MPs go back into the treasury.
So if you have 4 social production but aren't building any social projects or ships, you will keep your 4 bc.
That's as much as I understand the issue. What people do usually to balance their economy is devote entire large planets to harvesting money. The planet will have a large population, a high approval rate and plenty of economy boosting buildings.
#3 - Try running a constructor into an exsisting starbase. That will take you to the upgrade screen where you can apply your modules.
