Hi there.. Its hard to understand what your question is in some of it i think, that why no one has answered.. With the automatic mapping, i wouldnt use for the house, you would be better of useing planar. Apply the texture you want for the house. The select all the faces on one side, and the add your planar map. Then just adjust it and resize it until it looks correct.. With automatic mapping isnt too bad if your useing programs like Deep Paint, and paint your textures straight on. Look around on the net. Theres some could tuts on planar mapping. Try mckinelys site.. He has some on there i think.
As for the other questions, try rewording it, and post again.
There's nothing normal about normals. In FACT i think the are abnormal.
