Sometimes the simple solution is the best one (at least initially). Track HW and all those other process things because they are important. Parents can access them. If they are important, you should be able to show kids the relationship between them. Just set those categories to 0% of the grade.
Some people will put specific targets in the grade book. that's a little much for my organizational skills. If you are designing your assessments using a thoughtful process like the TOS and communicating that info to the student with the feedback given with assessment, I don't think it's necessary.
