One tonality change + minor grammatical changes

In "Review Available Tools and Resources," (1) adding hyphen to "organization wide"; (2) in key action 2 description, adding a comma and changing "impact as" to "impact on"; (3) adding a comma to key action 3 description; (4) in key action description 4, striking "even" from from "Websites, forums, mailing lists, and even books are invaluable."  My inner librarian weeps to see books spoken of so.  :-)
