Do a "sudo apt-get install linux-image-server".  This will install a PAE enabled kernel
that can recognize your extra RAM.  I run this successfully with a server containing
16GB of RAM.

As to your RAM usage, that sounds normal.  Our users typically consume between 200-350MB
RAM while using OpenOffice and Firefox.
