Also tell us what timeline (if you use 1, like dark empire) you are using. Generaly when i play it on ROTJ mode for the rebal alliance, for fighters i build X-Wings, Corvettes i build heavy correlian Gunships, Frigates i get a combination of MC 40s for the heavies and Nebulan Bs for the normals. When it comes to capitals the extra 2 grand for the liberty is well worth it. In this game you dont realy have to worry about the units such as cloaks and repair units. Hope i've roughly answered your question or sort of got an idea what you want to know.
