Any problem with this apt setup?

Code:
onemyndseye@exodus:/etc/apt$ cat apt.conf
APT::Default-Release "testing";
APT::Cache-Limit 20000000;
Apt::Get::Purge;



onemyndseye@exodus:/etc/apt$ cat sources.list
# /etc/apt/sources.list for Knoppix
# If you want to do a "full upgrade", you should first
# upgrade the Packages from Debian/unstable (KDE & Co.)
# before doing a (dist-)upgrade for Debian/testing.
#
# See sources.list(5) for more information, especialy
# Remember that you can only use http, ftp or file URIs
# CDROMs are managed through the apt-cdrom tool.

(Yeah yeah...... I know I shouldnt have my user account set to NOPASSWD in /etc/sudoers

Am I not understanding .... or does this put me current upto Etch. ? (apt-get upgrade and dist-upgrade already preformed)
