<p>How do I change Oracle from port 8080? My Eclipse is using 8080, so I can't use that.</p>

I assume you're talking about the Apache server that Oracle installs.  Look for the file httpd.conf.
Open this file in a text editor and look for the line
Listen 8080
or
Listen {ip address}:8080
Change the port number and either restart the web server or just reboot the machine.
