I think it's notable that Lupin's bag is old and worn, with "Prof. R. 
J. Lupin" embossed in gold.  The lettering is old too, sorry I don't 
have the book on hand to quote, but I read that over and over to make 
sure I read it right.  It indicates to me that he's taught before, 
somewhere, so it's possible that he's got years of experience 
teaching DADA, and he certainly seems up to the job.  Another 
explanation for the bag, however, could be that his father or 
grandfather had the same initials and had been a professor.

When I read that it crossed my mind that something more was going on. But I
quickly realised that the text could equally well be describing an old bag
that had recently had the name/initials added to it. The bag being old
doesn't necessarily mean that the lettering on it was old.

As for why he was DADA. Personally I don't see DD as a man who knows
everything, but a man who knows how to prepare for a range of eventualities.
I suspect Lupin was brought in as DADA teacher not because DD had included
him as part of an intricate plan, but because DD instinctively new that
having an old school friend of SB around could prove useful.
