I am more familiar with unices but I'll try to help you on windows. Check your services that are running. I cannot remember how to do that step-by-step on windows but it's accessible by the control panel and is called "services". Stop the tomcat services and possibly you can stop them from being automatically started when you reboot as well.
Once you've accomplished that,
you should be able to look for the server.xml file which would be in the /usr/local/tomcat/conf directory on unix. Again, your mileage may vary if tomcat is installed in a different directory. It should usually be in a /conf directory under tomcat though. To be safe copy this file before you modify it. Then modify the copy of the (actually the one named server.xml, call your copy server.xml.orig or something) file and change the ports to some not being used. If you only want to have one version of tomcat running, you could use the default 8080 unless you have the oracle web server or something else using that port. Try 8088 as an alternative. The way I learned all of this was to read the tomcat documentation and books on configuring tomcat.
Good luck!
