The only package I found installed that relates to kde4 was "oxygen-icon-menu" which
I did not uninstall as system has never been anything other than LXDE solo.
If you have the kde4-4.6.5 package installed, you need to remove it and install the kde-4.8.3 package. This is not about being LXDE solo. It is about being fully upgraded, so that you do not run into problems in future.
While installing package apt-sources-list-1.0.2-1pclos2012:
warning: /etc/apt/sources.list saved as /etc/apt/sources.list.rpmsave
gtk-update-icon-cache: No theme index file.
The first part of the message is telling you that your new sources list was installed and a back up of the old created. If you had a PASS account in the old, you can transfer it to the new. Otherwise the old is not really of any use and can be deleted.
The second part can be seen as a null message; i.e. it can be ignored safely.

Note: A link to launch an application is a link to its .
desktop file. These are found in /usr/share/applications.
