What mod can anyone recommend to try next?

I understand a bit better now about the buildings, thanks Alneyan, but another question now, I captured a planet, and I wanted to move some of my pop over to it, I have a troop transport (the one I used to capture the planet with) And I can not load one person on to it :S this may be something obvious, but what did I overlook or do wrong?

Thanks
