So this is the first time you've explained the real problem you're
trying to solve. It certainly helps explain, a little bit, at least,
which direction to point you for solutions.

Right. If you want to access the model itself, pass the model to the
template, not the output of __unicode__. The __unicode__ method returns
a string (a Python unicode object).

Looking at Django's forms module would help you here. There are lots of
classes and functions for creating HTML forms and converting models to
forms.

It looks like this should be working fine, printing out the values of
each of those attributes.
It sounds like you were hoping the BooleanField attribute would display
as a checkbox, but it's not a form field. It's model field: so it holds
data and can be used to access that data. If you want a checkbox, you'll
need to create a form object (you could do that manually in HTML, but
it's much easier to use django.forms).

What do you mean by "more fields"? The queryset returns a bunch of model
instances and you can access everything in the model. What else are you
after here?
Have a read through all of the documentation under
http://docs.djangoproject.com/en/dev/topics/forms/ and see if that helps
you do what you're after.
