If you want to install java in Debian, first try OpenJDK. It will do almost all that Sun/Oracle Java will do, without all the installation and update headaches.
Once again as root:
apt-get install openjdk-6-jre
And to get the java browser plugin:
apt-get install icedtea-plugin
If you need java for live chat, these packages should do the trick, as I use live chat and don't have the Sun/Oracle Java installed.
BTW - Great news that you flash is working. I've achieved success with the copy/paste of commands from forums myself, and, that's why we post the code. Just makes things easier.
