Which means that you did not install the info files in a place where
Emacs can find them.  But the same information is also in the
"INSTALL" file.

NO NO NO!!!!!!!!  PLEASE adhere to the instructions.  Your
installation command placed files into site-start.d, and _those_ files
need to get _loaded_ by Emacs in order to start AUCTeX and
preview-latex.

Please clean up the complete mess you made by now, remove all files,
then reinstall.

You have a standard Debian Emacs installation, so please just remove
all traces of your own AUCTeX installation, then do

apt-get install auctex

as root, or get your system administrator to do it.  This will install
and activate AUCTeX, and make it easy to upgrade to later versions.
This is by far the most sensible option at your level of experience.
