I do have some ideas that may differ but Well done, Thanks for sharing!!
You have downplayed the use of page rank. No reason to start a campaign for a term that is already being dominated by high page rank sites.
For example, if I want the term "porn" and the front page of google has sites getting the term with a pr "0" It is available for the taking. If the front page of google is full of high page ranked sites it will be difficult....
As far as meta tags, if the term is not in the content do not use it in the meta tag.
Keyword meta tag is no longer used by Google.
