Potioncat:
I don't think the prank had happened yet.  I'm not sure if it's canon 
or my impression, but I think James changed after the prank.  It may 
be that by 7th year he had changed, which leads me to believe the 
prank was in 6th year.

Whether he knew the nicknames at the OWLS, I 'm not sure. But I'm 
sure he knew them by the map incident.  Knowing the names wouldn't 
mean he knew why the names fit.
