I suspect that a chunk of that ram usage is for file buffers. Use the
command 'free' to get a better idea of actual ram usage.

Using all of the system ram is a good thing, but using swap is not. If
after an hour of regular computer use you have more then a few MB of
swap in use then you know that a ram upgrade will benefit you.

Ubuntu by default uses Gnome. Gnome uses lots of memory. On my
Debian/Etch system Gnome is using almost half of the 140MB of ram
actually in use. Because of the way Gnome is built with its many
libraries loading even a single Gnome app will load many of those
libraries using more ram then you expect. Gnome is not a good
environment for systems with small ammounts of ram.

Ubuntu also has an XUbuntu variant which uses the XFCE X11 desktop
environment. It requires less ram. You can convert your Ubuntu system
to use XFCE. From http://www.xubuntu.org/get

   Install Xubuntu from Ubuntu

   If you have an existing Ubuntu, Kubuntu, or Edubuntu installation, it
   is possible to install Xubuntu and retain your current
   installation. To do so, just go into Synaptic (or Adept if you use
   Kubuntu) and install the xubuntu-desktop package. There you are! Next
   time you login, you can choose Xubuntu from the Session menu on the
   login screen.
