Adjust TA first, right?

WRONG!

PH should be adjusted first. The reason is that your alkalinity will change, if you adjust your pH, and what was a problem, may not be one, once you fix the pH.

OK, so If I want my PH to be 7.4 to 7.6, and my TA between 100 and 120, I should add acid first to get my PH down, and then add baking soda to bring my TA up? Should I wait a certain time in between?

I'd just leave ph of 7.8 alone. If it goes any higher, then I'd try and drop it some, but anywhere 7.2-7.8 is OK. And, your alk is only a little low. Go slow with the baking soda.
