On the textures in Blender. I think it might only export the main window texture coordinates from the image editor. What I do is open image editor, select all the vertices I want to texture in edit mode of the object and choose an image in the image editor. For repeats, I go into the image editor window, select all the vertices, and then "s" size them larger, which makes them repeat. You can also cube map etc, by choosing "u" in the 3d window.
