Lighting is only applied to objects that have textures set to be non-alpha (i.e. RGB) , and have the shading flag set.RGBA and A textures are hard coded as not being lit. I'm not sure what the implications are to change that.
If you have a texture with no transparency, and its set to RGBA, that would also probably not help lighting. It would probably help performance a little if you changed it to RGB as well.
FYI: Ambient light is the base level of lighting applied to all objects, and is constant. Infinite lighting is a directional light source, that makes the shading happen.
If you have 0 Ambient lighting, and resonable infinite lighting you will get very high contrast shading. If you have 0 infinite lighting and a resonable amount of ambient, you will end up with flat looking objects.
