There is an obvious problem with your question I can help address: ISO 20000 relates to very general ITSM requirements to certify a management system, not to the specific best-practices used to implement it (or good practices, or bad practices).
What you probably mean is that you would like to review samples of ITIL-process based policies that correspond to specific 20000 required policies, or to processes that don't specifically require a policy. It is easy to tell which are which since the standard will cite that a company "shall" implement a certain standard (complete list in table below).
Actually all the documentation required isn't so difficult to map out using the same approach. Writing out all the individual specific 20000 requirements ("shall" statements) isn't quite so easy because some are a bit vague and come in multiple part statements, and some are only functionally implied by other clearly stated requirements.
To get to the point of your question, the easiest way to find policy examples is to use Google to search for a certain policy (eg. "service management policy"), also checking search results by adding terms like "template" or "example." As far as I know there is no site that makes a point of offering a lot of good policy or procedure template examples for free. I don't think you will find much, or anything of good quality, but you never know.
From what I've seen of "toolkits" or related purchased resources you would really need to pay a substantial sum for a competent source to provide any decent starting point. Even then since policies and procedures (and records, and practices) are company-specific these would only be re-writes of ITIL framework into a document template form. This is the kind of thing consultants develop and sell for a substantial sum, along with assistance in customizing and developing them.
It's not even close to what you are looking for but if you haven't done so take a look at Cobit, reference content designed to support auditing service management. Some of it is free on-line, with more content and other resources only available for paid members of ISACA.
