This might not be the most popular response, but I would suggest avoiding regular squats and deadlifts for a while, or at least avoiding rep ranges in those movements of less than 15. I'm all for heavy lower body lifting, but a herniated disc? Not something to fuck with.
If I were training you, I'd have you focusing on single leg work (step-ups, single leg squats, lunges) where there was much less chance of lumbar flexion (which would aggravate disc herniation)and not a lot of axial loading of the spine in general. Lots of core work, isometrics, etc. until your back was more or less pain free for a few weeks. Then introduce squats/DL variations in higher rep ranges WITHOUT belt support. I'd save a CW program for when you were more healthy.
