Usually the browser remembers what you entered.
Maybe I don't understand the question.

? Of course there is. In python you can do
REQUEST.form.set('foo', 'some value')
Or you can arrange for the user to visit a url that
includes it in the query string, like
Either way, you still have to arrange for the
form to show the value, so you still need
the tal:attributes expression.

If you don't want to do it by hand, maybe look at products
like Formulator and Archetypes which do a lot of
form layout work for you.

I think you've misunderstood that. How do you expect it to work?
Default values in a form are an example of presentation
of data. This is certainly within the domain of ZPT.
It is not business logic.
You can't present data without somehow telling the template
what data to present.
