Importing and *using* Lightwave and 3D Stuidio

I’ve managed to import some meshes from Lightwave. The ones I have currently imported are Klingon Bird of Prey model from the Star Trek series.

The problem is that the meshes are all sperarate. There is a LWS, Ligh Wave setup file that comes with the Mesh, however, I can’t see a way to import this. Is there a way to do this, otherwise, if not, is there an easy way to join meshes, to figure out which textured go on which parts?

I have had no luck importing 3d studio meshes, the Python screen comes up with an error. Many Thanks.
