No. This is for most situations CATALINA_HOME. The only situation when it is not so is if
you want to have one Tomcat install dir and multiple instances or possible test configuration.
In tha case, each instance would have it's own dir with ./config ./webapps ./work ./classes
./lib and ./common dirs. They would all share the same CATALINA_HOME.

Tomcat, most definitely.

These are for manual startup/shutdown. Of course, on UNIX we use that for boot/shutdown operation
as well.
