Doubt that any of this really qualifies as "good" - but a few hints.
1. Check out Dick Baldwin's tutorial on lighting on his web page. It's good on the basics.
2. There are also a couple of good general lighting tutorials in the Blender tutorials. The information there applies to general 3D lighting, not just Blender.
3. If you are going to try for unusual light effects, delete the light that is placed automatically and place your own. I would also recommend not using a general directional light - as you note, it seems fairly unpredictable.
4. I ususally also make the sky dark and turn the world lighting way down - but this is an artistic choice.
5. Play with the "emissive" and "specular" parameteres (in seldom used properties) for the object being lit.
There is really no good way I know of to save a lighting setup other than to save the entire world. You can save the individual lights and a method to move them to their starting positions (see another of my posts in the forum) - but that's pretty cumbersome.
I played a bit with your world and have attached the result. Nothing great

- but look at the light and parameter setups to see what I did do with the options.
