Unless you need to backwash in the next few days, I would put take the CYA out of the socks and put it in the skimmer........I'm sure it will dissolve faster.
Because you have no effective level of stabilizer (yet), I would suggest putting the Cl (up to 12-14ppm) in at dusk. Test again just before you go to bed and bring it back up to 12-14ppm. Test again in the morning to measure your overnite loss....when it's less than say about 2ppm, your pool should be sanitized and CC's gone.
The CYA will be slowly increasing in your pool as you do the above. You should probably be able to maintain a 3-6 maintenance level in your pool from then on.
