I think you'd be better off waiting till it's clear before you bottle, clear enough to read a newspaper through. No need to add any more yeast, there will be plenty in there even after it clears. If you bottle before it's clear, you'll get a lot more sediment in the bottles. You should be OK on the alcohol levels with Nottingham yeast. When you do bottle, prime it like beer & wait a few weeks, should carb up just fine. Regards, GF.
