Would you please clarify your questions and give more information on your problem? It could be anything why this does not "show correctly".
And you should be able to rotate quads if you map TGA textures to them. What are you trying to rotate, the texture using the GL_TEXTURE_MATRIX or the quad itself? The latter would be a problem independent from the texture.
