I'd start with getting some chlorine in there first before your pool turns green! It can happen faster than you realize! For the first few days until you get a CYA reading, you'll have to add bleach 2 or 3 times per day because it will quickly be lost to the sun. I'd add enough to get to about 5ppm each time. Hopefully, that will keep you from going all the way down to 0 between additions of bleach.
Then, you can do the other things. You can actually work on these items one right after the other with no problem. If you are going to add CYA via a sock in front of the return jet, move the sock out of the way before you add the acid.
Sounds like you have been doing your HW and have done some reading and have a pretty good handle on this. Good for you!
The only thing you didn't mention was the alk. Have you tested that yet? If not, no worries -- just test it when you get a minute.
Do you have a good test kit like we recommend?
(BTW - you don't need any Borax. Borax is used to raise ph and yours is a little too high.)
