PBL takes you to "Project Based Learning" where you can not only find tools to build your checklists, but there's plenty of good information about project based learning. :) Shocker. Just click the logo once you get there.
Rubistar is an excellent starting point for developing your rubrics. There are lots of options to choose from here, but I typically visit the "Multimedia" section for help when I'm working a rubric involving the integration of technology.
