... my understanding is the dynamic range functions are applied to RAW as well as JPEG ...
The RAW file is just the digital equivalent of an image taken on slide or negative based purely on shutter speed, aperture and ISO - just like a film camera. It isn't processed at all. Most software packages, however, use the camera settings for reconstituting the image for further processing (or development.)
Most DSLRs take a 12 bit image. Newer ones including the K-5 take a 14 bit image. By combining images in suitable HDR software that can be extended further up to 48 bits.
There's no reason for HDR shots to look over the top. Without HDR my original jpeg file for the recent Buildings comp looked like this:

The 5 exposure HDR makes a world of difference:

Even with contrast AF enabled there is still some mechanical action going on between shots and I can feel a bit of vibration when hand held. Is that the aperture being stopped down?

I'll do it for you: Pentax DL2
Remember though, just because the images can be viewed freely doesn't mean they can be reused elsewhere without permission from the copyright holder. Personal use would surely be fine though.

it isn't on the K-5 without the use of third party software

When taking the photos, it would make sense not to set everything up at the highest resolution. Better to start low and work up!
For the record I haven't tried any of the above software for this purpose. I think for starters I'd go for MakeAVI. It's open source software and has a 96% user rating and looks simple to use!

Anyhow, that's a really nice twilight photo. That one certainly doesn't need any extra detail in the dark foreground. The picture is of that interesting dark red sky so detail in the foreground might even detract. There's nothing wrong with silhouettes!
As to whether highlight and shadow correction were turned on would make any difference, personally I doubt it would have made much of a difference either way. That function is mainly useful on sunny days (remember them?!) to help keep detail in the shadows and to stop highlights being burnt out. You don't need detail in the shadows here and the sky certainly isn't burnt out!
