You are welcome.
In your research towards implementing some of the more advanced aspects of OmniFocus I would suggest looking at a few things.
- David Sparks website as he is both a Mac user and a lawyer. He has a great website http://macsparky.com and his book "Paperless" is well done http://macsparky.com/paperless/.
- A book "Creating Flow with OmniFocus" by Kourosh Dini here http://www.usingomnifocus.com. He also has a new book "Workflow: Beyond Productivity" I have not had a chance to read yet; which is here http://www.masteryinworkflow.com.
- A solution and resource by Chris Sauve to create OmniFocus projects from templates is very useful http://cmsauve.com/projects/templates/.
