Hi and welcome
The syns are the same on EE as on red and green, if you look in your book you need to take the highest syn value, out of red and green so for example say a sausage is 5 syns on red and 8 syn on green and you are doing EE you need to use 8 Syns as your syn value. The main difference between red/green and EE is that you are only allowed 1 Hex A & 1 Hex B and at every meal you have to incorporate 1/3 of your plate super speed food, so if you have a steak & slimming world chips (so 2/3 of your plate) the other 3rd needs to be filled with SS Veg or Salad for example.
I hope that helps (and that I have explained it right and correctly!!)
I can't help with the cottage cheese question sorry!
Good luck on your journey, you will do great
