Yes, it is.
You can find all information from
ISBN Users' Manual (ISBN-13).

It is the must.
check 10 and 13 digits automatically.

> * re-calculate all previously entered ISBN ?

Need not change any issued 10 digits ISBN.
Unused 10 digits ISBN still valid even after 2007, january.

> * rewrite show-isbn-with-dash sub ?

Koha need minor change to handle this.

> * that's all ?

Almost.
