Publish settings compresses PNG files in the FLA globally. By doing this, you're setting a uniform quality % to all bitmaps. I don't like doing this because you can optimize certain images more than others, and because PNG files take up more space on a HD. Ultimately, PNGs also increase the overall size of the FLA (not the SWF).
If you want to automate the process, you can either import all images as PNG and set the desired publish settings, or you can optimize your JPEGs in a photo editor and import them in Flash with their imported JPG data. I believe Macromedia usually suggests using PNG, though I prefer the latter for size reasons. Also, if you decide to dynamically load your JPEGs, the SWF can't control the bitmap compression at runtime.
