Problem using Views with Category module

I had earlier posted this on the author website of the category module; don't know how many Drupal users use the category module.

Anyways here's the problem:

My first problem is that I can't get views to display on a category page. Is the "taxonomy: term ID" a necessary argument to generate a view or can it be done without? (as expalined by the author to create a view here - http://category.greenash.net.au/category_views_usage)

My other problem is a container contains more than 2 categories. And each of these categories cannot have the same view displayed. In this case, Can I generate category views as blocks and then use it to display them in the relevant category page? or is there another route to use different views on multiple categories belonging to the same parenti container?
