In this case, I just used “Auto-Warm” for the White Balance setting, and then adjusted slightly to match.

It just depends on your tastes and the final medium. For posting lower-res (like Instagram, for instance) you just need to be careful that you don’t over-sharpen the original, and then use some form of output sharpening on the final file resolution… Lightroom has a built-in output sharpening in the export module, but I prefer to use something called an “unsharp mask” on the final size… you can do this in Photoshop, or you can get a plugin called “LR/Mogrify 2” that includes an unsharp mask that you can setup in Lightroom’s export module.
