P TEW- Here are a couple of images tht might be able to assist you.
In the following image make sure you have all of those option highlighted in red clicked, you should not have anymore problems with the exporter after that.
next image shows how to flip normals. it is evident that you have some normals that decided to flip on you. you have to go back in to blender and then go in to "UV face select" and chose the faces that are see through and then go back in to "edit" mode and follow the next image.
That should fix all of your problems minus the scaling issue. You need to zoom out as far as you can and then scale the heck out of it. you may notice some camera clipping, don't worry about it scale it little more and then export it. it should then be about the right size, you may have to edit the scale a bit in the segment editor or the .fps file.
Cheers,
Dave
