Hey Chris, replying here for other people who land here looking for the same.
Your best bet would be to print something suggestive within each method of the classes BaseModelAdmin & ModelAdmin, you can find them under site-packages/django/contrib/admin/options.py
This is what I got, but keep in mind that this is the general order, not all methods will be executed for every action in the admin interface.
