With regard to the bump map - my understanding is that if you change the mapping for the color, it won't automatically change it for the bump. You need to go into the function editor to do that.

In the function editor, make sure 'bump' is selected and you should see a texture map node with your bump map in it. The little node above it is the UV coordinates node and if you select this you can change the mapping from Automatic to Faces.

I wouldn't have thought this would account for the lack of bump though. Are you using the same image map for colour and bump? If so, you might want to load the map into a 2D editor and convert it to greyscale, then increase the contrast. Save it back out under a new name and use that as the bump map.
