If you're just doing Clean Hands, as long as you use sleep darts and choke people out, you should be good. The side quest makes it harder because you're running into more enemies than you need to, and you'll have to worry about weepers at the distillery in the next mission. You have a limited number of sleep darts, meaning that you'll probably have to be stealthy as well or risk using them all up. You can buy them from Griff, but he charges much more coin than Piero does.

As for the ending with Granny Rags, if you use a sleep dart on her instead of killing her, you should be fine. You can't kill her and get the achievement, though.
