Don't overthink it. We tend to want to over-prepare, pack too much, stock up way too much, read every single thing we see online and then obsess about any negative thing we see. You're ready. You've finished all the hurdles, you've been approved, you have the date. There's not a lot you can do 2 months before your surgery.
Maybe start looking at different food tracking apps to see which feels the most user friendly to you. Look through youtube to find some good GENTLE workouts for the first 6 weeks post op and save them to a private playlist for yourself. Make sure you have some loose clothing for after surgery. I bought one of those big, cure jugs that is 64fl oz so it would be easy to measure how much water and fluids I was taking in (admittedly, at first I was barely getting in 3-4oz at a time, but I quickly worked my way up and was glad I had that because it was cute and convenient).
Make sure you have plenty of Miralax on hand and possibly, if things are really plugged up, a laxative/stool softener combo. And I made sure when I was drinking broth, it was bone broth because it has more protein. That's really it.
