Seems you're following two different (and incompatible) sets of
instructions, and trying to merge them into one system.

You'll have to decide whether you want Apache httpd in the mix or
not. The above extension for Apache Tomcat is only needed if you don't
have httpd running at all and instead rely on Tomcat as a webserver on
both ports 443 /and/ 8443.

Either way will work: The dta extension allows to run only one server
process (Tomcat) instead of two (Tomcat and httpd) but is only
officially supported for Tomcat6 (although there's a contributed
extension for Tomcat7 that seems to work just fine).
Getting authentication for ECP set up seems a bit easier with httpd in
front, but can also be done with Tomcat solo.

In any case you'll have to either remove httpd from the mix and
configure Tomcat for https on port 443 also (i.e., running only
Tomcat) /or/ remove all connectors from Tomcat's server.xml except the
AJP one on port 8009, and restart both httpd and Tomcat (running httpd
on all external ports, and Tomcat only internally).
The second variant seems a bit easier given your existing configuration.
