How would I create a "quick" checklist content type? (see details)

Howdy,
A coworker and I work really well with checklists for different types of projects. An example would be a list with all the steps required to set up a new Drupal website, where we would check items off one at a time. Currently these lists are in paper, but why not make a Drupal project out of it? What's the best way to get started?

I could create a "Drupal Website Task List" content type, and create a field for that with checkboxes. Almost there, and it works great. Now I'm wondering how to make the checks edited more quickly. Is there an ajax dhtml popup or something similar to make updating nodes or parts of nodes (like just the checklist) quicker?
