Can I upgrade my system to be all testing just by adjusting
/etc/apt/sources.list?
yes, just put testing instead of stable and then run apt-get update
apt-get dist-upgrade
I noticed this:

Note that tracking the testing distribution of Debian can have the side
effect of delaying the installation of packages containing security
fixes, since such packages are uploaded to unstable and only later
migrate to testing.

Is there anything to do about that?
