Does PIL resize to the exact dimensions I give it no matter what? Or will it try to keep the aspect ratio if I give it something like the Image.ANTIALIAS argument?

Yes it will keep aspect ratio using thumbnail method:
image = Image.open(source_path)
image.thumbnail((500,500), Image.ANTIALIAS)
image.save(dest_path, "JPEG")
