I may have underestimated how quickly people can rush through the story mode. Still, I'd expect most people to replay a couple of particularly bad days and just generally dick around a bit. In which case 20 hours for 100% (fruits and otherwise) still seems like a good rule-of-thumb number, though 'absolute minimum' was an exaggeration.
I think there also might be slightly alternative endings for extra fast runs, as well as no/few Pikmin death-runs. Could be wrong though, have yet to make one.
Asked and answered, but I'll reiterate and clarify. There are, in the form of data files. Most of those are simply tutorial, but there are ten secret ones as well, a couple of which are very well hidden.
There are also a few optional collectible power-ups/suits.

FOR THOSE WHO HAVE ALREADY FINISHED THE GAME:
Are there or aren't there other collectibles in addition to fruit?
