Answers to question 1 can be found at the following links...

SQL Plus Release Notes, Section 5 new features
SQL Plus Documentation

As for your second question... query management is all about managing queries in that you track and update queries to be as efficient as possible as well as who can access those queries and what they can access.

Examples might be...

1) Restricting insert/update queries to only senior management between the hours of 9-5.
2) Constructing query views of data so that the VP of sales can see the total liabilities and revenues world-wide while the director of North American sales can see only sales figures for locations in North America.
3) Changing a query to use an inner join rather than a nested select to increase efficiency.
4) Changing a query to make use of new indexes on various tables.
5) Creating or changing queries to construct or update reports.

Just a few examples. :)
