If I suspend the stainless forms on bricks, the forms will bend and warp. So I suppose you would use kiln shelfs to suspend them, but wouldn't that in turn rob some of the heat from the piece?

I thought that the annealing temp was higher - around 965, and just found out today the correct figure. The reason for the high soak is advice from glassmakers that soaking 25-35 degrees higher than the annealing temp for four hours is helpful. No you are not missing anything, but I was.
