Sounds good.

As to assets, its a pretty broad term. Any ships your group owns should go there (remembering you can also use non-military vessels for transporting your troops) as well as any planetside facilities of any sort that aren't your main base. Also any regularly used contacts. In your case that could be pre-existing non-player long term employers, people that regularly supply you with arms, or any other folks that you are regularly in contact with.

For specific examples of what others put there, you could look at the other accepted sheets (links all in post #2), that might give you some clarity/inspiration?
