Is it possible to change these frame rates to 29.97 so they'll stick? I can change the numbers by using the TAB key to advance to the next field, but when I click on OK or APPLY, they revert back to 25.
I've done this, but now that brings up another question: If the original setting of 25 FPS remains in the configuration file, does that have any adverse effect on the frame rate whatsoever?

No - the framerate of the export is what you specifiy it to be at the time of export.
This is subject to the combinations of framerate, resolution, bitrates and quality settings being compatible with the export format - you will usually get a warning that one or more settings are incompatible if this occurs.
