The easiest way to run programs automatically when KDE starts is to use the Session Management feature of KDE. You can setup KDE exactly the way you'd like it to start every time you login.
Choose K-Menu → System Settings → User Account from the Desktop Menu System. Click the Session Manager button on the left. Ensure that the Restore manually saved session checkbox is enabled.
Launch all the applications you want running everytime you log in. Once you have everything set to your satisfaction, click choose K-Menu → Save Session. Every time you start KDE, you will return to this configuration.
Another method to do this is to copy the desktop entry of the application you want to autostart from /usr/share/applications to the ~/.kde/Autostart directory.
NOTE: Desktop environment is called KDE and the file manager is called Konqueror).
