It updates the sources list only. It doesn not download or install anything.

Question 2).
Apt get install Xfee86 ..
will this install the newest version of Xfee86 video drivers?
Knoppix already uses the latest version of XFree86. As fas as what is installed with XFree86 I would suggest going to XFree86.org and reading all about it. You will already have DRI and the Mesa libraries installed. You of course may need other drivers.

After it is install are their any additional configuration that needs to be done.
(other than restart)
Maybe, maybe not- it's up to you. Most people aren't happy with their fonts. It's also likely that you will need to adjust your /etc/X11/XF86Config-4 file. Again -go read what XFree86.org has to say about tweaking and installing. They have alot of documentation.

Question 3).
Can or does apt-get update or install newest kernal updates?
If show what is syntax?
You can find complete documentation on apt-get here

There is also "the Debian way" of installing a new kernel here
