Derek, I'd say you are on track with your learning curve -- that's a nice "early shot"!
I guess I personally would try more Fill/Shadow/Dark boosting for the foreground, simply because, with the sun still up, I assume that what you saw would show more light on the scene. Of course, these are the challenges we face, and bring out the real value in Raw shooting!
As to the sky, I don't know about fussing over the clouds. That's a balancing act. You can play with a Gradient -- one of the great things about a Raw workflow is that you can't "wreck" anything, you can easily undo/redo something. In fact, one very useful tool in Lightroom is the ability to create Virtual Copies and create new versions with different things applied -- like the version above, then a version with a gradient.
But I would suggest tinkering with the blue sky a bit -- the color balance in your After shot is different, not as blue. Maybe playing in the HSL toolkit will get some cool results!
