You'll see a bunch of 'dots' throughout the image: http://www.andymccurdy.com/resized_1.gif Here's the image resized again with your suggestion of converting to "P" mode and setting the dithering prior to saving: http://www.andymccurdy.com/resized_2.gif You'll see both of the resized images are pretty poor quality.
