A pound of brown sugar can add some nice notes. Consider using 1084 Irish Ale Yeast, it can handle higher ABV's than 1272. It also provides a more complex set of esters, which is good in a barleywine. Plan on a couple weeks in the primary. Couple months in the secondary with a finishing yeast if needed. Dry-hop towards the end, if you decide to.
