do i understand it right? You want to texture single faces of a cube in Vue. Not possible - sorry to say. AND, you haven't said which Vue version you use. If it is one of the Pro series (5 Studio or Infinite) you can do the following i think. Attach simple basic materials to each surface in Lightwave, bring that into Vue and change the materials to the ones that you want. Then make changes to the original lightwave object - Vue should then automatically recognise that there are changes made in the model and updates the geometry. AND will ask wether the original materials should be used or the ones that are modified in Vue. Let us know wether this works.
