I've never used Devonthink, and accordingly know diddly-squat about it. If the materials stored in Devonthink are stored in separate files which you can locate/identify, and double-clicking on one of those files in the Finder will open it up properly, then you can link the materials into OmniFocus. Just select the file containing the information in question in the Finder, then drag and drop it on the corresponding action or project in OmniFocus and you'll get an alias to the file in the notes field, which can be double-clicked to open the file.
