I'm sorry to hear that. My sister has Fuch's Dystrophy as well and also had a double cornea transplant, but it seems to have mostly fixed all of her vision issues. Time will tell if I'm in the same boat, but so far have no signs of it.
Great advice. Another point (related to 4) is don't trust your oven to tell you when it's up to temperature. The oven is measuring the air temperature and not the temperature of the stone/steel. I always make sure to give it about 40 minutes to heat up.
