NEW UPDATE!! Version 1.1 Released (see changelog)

It should not break any quests. Feel free to play through the initial dragon battle. If you find that the dragon does not show, run through the middle of the two wooden towers along the road. This should trigger the quest. After you kill the dragon talk to Irileth. She will advance the quest.

If you like Whiterun as much as me, try this: http://skyrim.nexusmods.com/downloads/file.php?id=9277

Think you deserve more than a s***** axe for slaying a dragon and saving Whiterun? Well think no more!
