I've parameterized my queries in my Classic ASP app, but am unsure whether I need to sanitize or scrub free text fields or if the parameterization is sufficient to prevent injection.
Not all sql stored procs are injection safe

If you use parametrized queries, you're safe against SQL injection attacks.
But not for XSS attacks; some user could to insert HTML content (think about <script>, <object> tags) into your database and, at some page, another user get that potentially malicious code executed.
