In terms of the fermentables, I agree with mloster on the buckwheat honey and the sorghum (or at least a portion of the fermentables) at flame out. I put your recipe into BrewTarget and as for the hop additions, 2oz of Bravo at 60 minutes puts the IBUs thru the roof, especially if you decide to add the sorghum at flame out. I am a hop lover, but at ~110 IBU (and that's with only with the Bravo) you may want to reconsider to the hop schedule and quantities.
