You can pretty much add the honey and syrups at any point during the boil. You won't get much flavor from the honey or Lyle's, anyway. The molasses will come through no matter when you add it.
I used to say this same thing based on experience but I have homebrewers bring me in beers made with honey that proves me wrong. I had a guy come in the other day who just used honey for priming and the flavor was unmistakably there. And he had only used a cup in 3 gallon batch IIRC.
