Based on tech research, race and what you have access to for crusade do this for decent production:
Stage 1 Build your space elevator adjacent to the capitol city. Build your core mine and starport adjacent to the elevator, add a factory adjacent to the space elevator/core mine if possible
Stage 2 Build your space elevator, core mine and starport adjacent to a new city for the +2 bonus to all
Stage 3 Build your space elevator and core mine adjacent to the new city and a fusion plant (or any +2 all con bldg)
If you have a land tile with +2/3 bonuses, always put the elevator on it and build the other around that.
For crusade there is no "Aid ship construction", what you have now is (manage shipyard + add more sponsors) as all planets now produce ship construction, whether you use it or not.
All of your shipyards should have 5 sponsors if possible.
