Need help identifying existing content

I've been working on identifying the developer documentation on 
mozilla.org that will eventually be brought under the Devmo umbrella.  I 
could use some help with this in identifying which parts are still 
valuable, which parts need updating, which items can be removed from the 
list, and what I may have missed entirely.  The list is here:

http://developer-test.mozilla.org/docs/index.php/Devmo:Existing_Content

Feel free to make changes directly to the page.  Any help and feedback 
is much appreciated.  (Many thanks to Nickolay for already helping out.)
