There is some on http://www.clearerthinking.org/
When I write I try to hit instrumental not epistemic (see here: http://lesswrong.com/r/discussion/lw/mp2/). And I believe there is a need for writing along the lines of instrumental guides. (also see: boring advice repository http://lesswrong.com/lw/gx5/boring_advice_repository/)
As far as I know there has been no effort to generate a sequence on the topic.
Is there a specific area you would like to see an instrumental guide in? Maybe we can use the community to help find/make one on the specific topic you are after (for now).
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
