How about reading the INSTALLATION document at java.sun.com that's on the same page as the SDK download?
As for the .bin file, just set it executable. Change to the directory where you want to install it, and just run the .bin script (you'll need to be the root user unless you're installing somewhere underneath your home directory). It'll dump the contents into a j2sdk1.4.1 directory (or similar).
Installing the browser plugin is fairly simple, if unobvious. Create a symlink of the plugin library in Netscape/Mozilla's plugin folder. For example:
ln -s /usr/local/j2sdk1.4.1/jre/plugin/i386/ns610/libjavaplugin.oji /opt/mozilla/plugins
I'm doing this from memory, so the actual paths may vary! I don't know what "Control Panel" you're referring to. Email me if you need additional assistance.
