Crikey, you are getting attenuation of around 77% there before factoring in the lactose with a British ale yeast? It's your beer, but I agree with others I think it will be bordering unpleasantly sweet with the lactose addition.
I noticed that you haven't put your hop additions into the calculator. How are you using them? That is a serious amount of Columbus!
