You are on the right track. I'm just going to tweak some of the amounts that I would add if it were my pool.

Adding that much bleach is only going to increase your chlorine reading by about 2.2ppm. The problem with that is since this is a new fill with no cya in the pool yet. your chlorine level is going to disappear fast, especially on a hot, sunny day and leave you vulnerable to an algae bloom. I'd suggest taking your chlorine up to 5 or 6 since it isn't going to stick around long. For the first few days, you may need to add chlorine 2 or 3 times per day. After about a week when your cya has had a chance to dissolve totally, you'll be able to test and dose it with bleach in the evenings only.

Your alk is OK at 90, but if you want to take it up just a little higher, then the amount you listed is fine.

I always like to aim a little low on cya. Easier to add more in a week if you aren't where you want to be than to overshoot your target. Maybe a little less than 76 oz. Then, retest in about a week and go from there.

Since your pH is so low, I'd add one full box of Borax slowly to the skimmer breaking up any clumps. After 3 or 4 hours of letting it circulate, retest pH and add more as needed. Anywhere between 7.2-7.8 is ok. I like between 7.4-7.6 for my pool. I wouldn't add 2 boxes all at once, though. It is usually better to go with smaller doses rather than one big one.

Hope this helps!
