Gerry,
As you read and learn about post-processing, the best advice I can give is that you rigidly adhere to an image-editing workflow that is consistent with best practices. If you change your workflow from image to image, you'll never get consistent results and you'll slow your progress through your learning curve. Rather than "play" with this and that software capability, use a disciplined approach to mastering each part of a best-practice workflow in order and one part of it at a time.
Without getting into the details of an ideal workflow because some of them can be up to debate, consider the following general approach:
Global Adjustments
- Color space
- White balance
- Exposure
- Saturation
- Levels and Curves (this is where you'll get most of the pop you asked about)
- Capture sharpening
Local Adjustments- Local brightness (dodging and burning)
- Local saturation
- Local sharpening
Output Adjustments- Color Space
- Image size and related details
- Output sharpening
