We've already discussed about propulsion, most of the other techs are pretty straight forward weapons, shields, ect.
But there are a few techs I'm not sure how or if to add

Ion Beams (and Ionic Torps)
Normal damage against shields, disable unshielded ships (can't move, can't shoot). Used to make boarding by a relative vulnerable shuttle a piece of cake.
Large ion cannon emplacements are the only "weapon platform" weapon seen in star wars.
