Playing with exposures

I have a steep learning curve with this new camera, there are more things to adjust than what I had on my old Film SLR. I like it, and it affords me more control, but just learning what is what is daunting.

I wanted to see if I could get a reasonable exposure of the sky with backlit clouds, this was the best result, but still may be a tad underexposed. My choice with this type of lighting is either to expose for the blue sky and clip a lot of the highlights, or expose to get detail in the highlights/brights and have a dark junky sky.
