1. Have you seen the following page?

2. A bad idea.

The recommended way is to start from default configuration and port
necessary changes from older version (reading the docs in the
process).

3. ConnectionPool comes from Apache Commons Pool + Apache Commons DBCP projects.

Tomcat 7 comes with two pool implementation. One is DBCP one (default).

Another is newer one, "Tomcat JDBC pool". Its documentation is
included into Tomcat User's guide.

If you are satisfied with the old one, there is no need to change.

Anyway each connection pool instance can be configured to use
different pool implementation independently. (Or a 3rd party pool
implementation).
