No need to logout and login in-order to run applications as root.
If a program is in your path, you can invoke it from the console as root. for example:
3) nano /home/user/textfile
nano is a quick console text editor but you may call any other app you wish (e.g. gedit [Gnome] or kwrite [KDE]).
I think in most cases there is no need to use dpkg directly.
Learn how to use apt-get (apt is one of the reasons why many people chooze Debian), google for apt howto. Then check out Synaptic which is a nice graphical implementation of apt.
