You look on target sweetcell. In beersmith for a 5 gal batch (without the ?? ingredients) I get:
color 24.7 SRM (brown)
OP, if this is 5 gal batch I think you're on your way to brewing a quad that needs about a 4.5 L starter.
What would you think about dropping the LME, dark grains, and brown sugar, and do something like:
9 lb Pilsen DME
1 lb candi or corn sugar
1 lb caravienne
Sounds like you want the hop character to come through but I wouldn't go too high on the IBU's.
EDIT - correction, calculated wrong when I posted. You could still do:
0.75 northern brewer 60 min
1 oz saaz each at 15 min, 5 min, and dry hop
that at least gets you more in style for a golden strong with
(correction) IBU 32
Per MrMalty about a 1.8 L starter for that.
