Been a browser for a while, so thanks in advance for all the help you have been giving me recently without knowing it

Anyway, I have been concentrating on Modelling since I began using Maya (which was only quite recently).
Now I have created some models and scenes that I am happy with I am trying to learn how to light them effectively. The only problem is that when I try to put lights in they just black everything out. Except the Ambient which just seems to make everything very flat.
I need something that will act like sunlight coming from a direction (so the shadows lay in the same way) and another that will act as a candle light, but will illuminate the scene (rather than just the top of the candle as it seems to now). Does anyone know which lights would suit these 2 light sources and could suggest some settings for them?
Also, if anyone knows any simple to follow lighting tutorials that would suit a complete beginner feel free to point them out

Many thanks again
