Yes, it maintains the history. This is a basic feature of Subversion,
one way in which it improves on CVS.

That doesn't copy any data, it just creates new nodes with the new names
and marks the old names as not in use any more. The amount of work is
proportional to the number of files moved (because each has to maintain
its history), but not to the amount of data in them.

I don't think it is, but it probably should be. If you read the book
and use Subversion for a while you'll just know the answer, but if you
want a single place to look it up, I don't know if there is one.
