One easy way to generate normal maps is to use the Nvidia normalmap and DDS plugin for Photoshop. Your results will vary depending on the source texture you use, but sometimes it does the trick. http://developer.nvidia.com/object/photoshop_dds_plugins.html

As for your second question, you only one want one normal per surface. A surface can only have one normal, after all.

If the textures are different, also the normal map changes. Naturally this is not true if you want to use a default normal map for all your surfaces...

a PLANE has only one normal...but after all, normal maps are useful when you want to fake more normals where they aren't (like on a low-poly mesh).
