Not a recommendation but it is what I've fashioned for tasking. It seems to be working ok. Probably more complicated than it needs to be & I'm always looking to refine, simplify it. Suggested changes are surely welcome.

GTD Inbox. All tasks entered here in a special form template. Some are linked to other items as necessary. For example: If I have to call the florist to place an order, I will link to that contact so I can always click on the parent to get the tel # & take notes in the contact detail area.
