That's about 67% attenuated... Which seems just slightly low to me. Depending on the kind of yeast and the size of the starter I would say you should probably expect 70-75% attenuation (or a FG of 1.025-1.021). So again, your pretty close...
-What size starter did you make for that big beer?
IMO on the max storage temp, I wouldn't go much beyond room temp. Maybe someone else can chime in on his temperature/storage question?
