My opinion, don't mess with either one. Most Tomcat users should not need to
change these values. What is your reason for wanting to change these?

Leave them alone. Don't touch either one.

My suggestion would be to put JDBC drivers into "$CATALINA_BASE/lib" or
"$CATALINA_HOME/lib" and put the rest of your JAR files in "WEB-INF/lib". It's
the simplest approach, it lets you easily hot redeploy your application and it
cuts down on weird class loader issues.
