If you added testing to your source.list then, you just asked dselect to
try to upgrade your machine to testing.  Of course it's going to go nuts
selecting new things...

No idea.  You might want to give aptitude a try though, since it handles
this sort of thing nicely.  Every package has a tree list below it of
how (or if) it's dependencies are satisfied...

Because a lot of people find dselect to be horrid and unusable.  Plus,
if you're already in a terminal, then typing three words to install a
new package is preferable to loading up a full-term app and wading
through the package list.

Also, apt ignores Suggests, which is considered a feature my some ;)

Personally, I'm partial to 'aptitude install blah'.  The simplicity of
apt with the nifty cruft-trimming abilities of aptitude.

As I said above, apt ignores Suggest's lines.  apt-get upgrade just goes
and has a look at the list available versions and tries to install the
latest version of everything.

apt-get -dfuy dist-upgrade works a bit differently, but is essential for
upgrading between diverging package trees and different releases.  It
does the same thing as apt-get upgrade, but will install new packages if

No idea.  Aptitude logs everything it does to /var/log/aptitude.log
though, which might be acceptable.
