The engine can do lots of things here.  Typically, it will at least accumulate
statistics for book positions.  Sometimes, it will mark the last move in the
book line if it turns out bad.  Sometimes, it may even back up and analyze a
line that turned out unexpected.  The ce can also be stored.

Crafty does it.  Maybe some others.  You can also import the learning data from
another machine output into crafty or even CAP data.

Yes.  Several programs do this including KnightCap, BACE, and Prophet.
