Hi Bebe!
Almond meal is just another word for almonds that have been ground into flour. So, you won't be substituting, you'll be using almond meal!
As for yoghurt, your calculations are correct. (And yes, for liquids, 1 mL = 1 g) But, there's a little controversy over yoghurt. Apparently, some of the sugars in yoghurt are "used up" in the culture process, so 7.6 g would effectively only be about 3 or 4. Some folk still count the full number but I think you are safe to assume the actual carb count will be considerably less than 7.6.
