Thats what the problem is. If you dont have a good uv map then you will never have a good texture layout. Try working with Lith more often or get UVMapper which seems to be a good program. Its hard to model in MS then not be proficient with another program then expect to have a good model with texture. I dont use Lith but I have used UVMapper and its a pretty simple program. You have to export then import back in using .obj format but worth the hassle if you dont use something like 3ds or Blender which have very good uv mapping tools.
