Yes I agree with you about being able to use the category meta tags fields but if you do this you would end up with the same page title on every page in every category which would be bad, if you were going to use this method you should add another field in the category db for page title. As far as what I mentioned about most search engines not reading meta tags is true. And the page title is the most impotant thing on your page as far as search engines are concerned. Or another method that would work is to use headers for meta tags and page titles.
