This overall type=* retagging task sounds like a great job for 
MapRoulette. [1] Casper, if you take a few moments to set up a 
MapRoulette challenge based on the queries you've run, you could even 
kick back and let others tackle the problem for you. In the past, I've 
been surprised to see challenges I've posted quickly winnow away. Your 
tagging suggestions combined with Mike's workflow suggestions would 
probably make for good enough instructions on that challenge.

There's also a "cooperative challenges" feature that lets mappers accept 
or reject a suggested set of tags based on aerial imagery, but I haven't 
looked into whether that would be appropriate for the more common tags 
that you've determined replacements for.

Hope this helps!
