Thanks to all those who replied. The solution to the first problem, was
that I had the program "biff" executed in /etc/profile. I deleted that call
and the message did disappear. 

The second problem is a little bit trickier. Although, the "xhost + name"
helped, the problem was with the DISPLAY number. I was using VNC server which
had a different display number. Once the SUed user exported the DISPLAY
number of VNC, then the user could start any X application.

Thanks again for all the help.
