2.2oz of brown sugar is not a lot and IMO you can really add it anytime during the boil or flameout. The honey, on the other hand I would either add at flameout or in primary as fermentation slows depending on how much flavor/aroma you are looking for. Boiling it for 60 minutes will essentially boil out any beneficial addition other than the sugar contribution.
If you are looking for good honey aroma/flavor, primary is the way to go. If you want a little less then flameout will provide a nice mellow hint of honey IME
