specs from phil website and using dt swiss spoke calc give
front 32h/3x: 281mm (using 12mm nips)
rear (double fixed 120mm) 32h/3x: 280mm (12mm nips)
try 278 rear, 279 front?
edit
i think for 3l/3t you want 1 or 2mm shorter for the spokes since they are straighter and don't cross as much? getting shorter spokes is better than too long anyway, you can just get longer nipples if you need to.
