free 3D Modeling software: http://www.blender.org/cms/Home.2.0.html

the tech tree is in here: \GalCiv2\Data\English\TechTree.xml

for tech requirements they use the "Requires"-Tags. Dont know if you can add multiple techs as requirement though.
At the moment every tech only has 1 pre-requirement. In doubt you will have to chain the requirements.

if its a planetary improvement for instance you then also have to add it to the PlanetImprovements.xml.

Just look at the other stuff inside the XMLs. Its easy to figure out how to do it.
