Odd, I usually get a mail when someone post here, but ohh, sorry for the late reply. Regarding the textures. Simply extract the ones in FS1 and Move them into the data/maps dir in FS2. The Tex names are equal.
I know those “Electric” lines looks cool, but they are a mistake from my side. Put them on wrong surface, and didn’t bother to correct it. Open your FS1 Lucifer model in model view, and you will see. If you want those electric lines, then it is simply a matter of exchanging capital02-02x with capital02-03x.pcx, where x is a, b and c, And you will get those electric lines.
