The above is bad. (Though not related to your original question).
You should not have servlet.jar in your application. Servlet API is
provided by Tomcat only. Tomcat had to ignore your jar.

The above logs mean that you do not have Tomcat-Native library, so
plain java (non-Apr) implementations of connectors are used.

Thus you are better to remove/comment the following line in server.xml
  <Listener className="org.apache.catalina.core.AprLifecycleListener" />

( When Tomcat-Native is used, startup of 5.5 would look like the following:
[[[
05.04.2012 18:47:22 org.apache.catalina.core.AprLifecycleListener init
INFO: Loaded APR based Apache Tomcat Native library 1.1.22.

Note that protocol implementation names are "Http11AprProtocol" and
"AjpAprProtocol" )

It is possible, but you better take a thread dump (3 dumps separated
by several seconds) to look what Tomcat is actually doing.

How to do thread dumps is mentioned in the FAQ

You mean "java.net.ConnectException: Connection refused"  exception?

It means that shutdown script cannot connect to Tomcat shutdown port
to send it the shutdown command,  regardless of the reason.

If it is because Tomcat is already stopped (e.g. you tried to shut it
down twice in a row) then it is normal and is OK.  If it is because of
any other reason then it is bad.
