Since your CYA is still pretty low and since you still have one pack of shock left, I'd go ahead and use it but maybe not the whole bag at once since your water is clear and you don't really need to shock. Add enough of it to raise your cl level up to about 6 or 7. Then, in the next couple of days, use the rest of it as your source of chlorine. When it is gone, just switch to using bleach. That last pack of shock will add some additional CYA. About a week after you finish using that bag of shock, retest your CYA and report it here.

Unless I missed it when I scanned back through your thread, I think your pool is clear. Your TA is fine, pH is fine, you have no CC. What do you need to do now? Go swimming!!
