comment Yeast for very high gravity (1.138) stout
I wouldn't aerate when using a slurry because aeration is for cell growth. The yeast uses O2 to synthesize sterols for cell walls. When you pitch as huge amount of yeast there's little need for cell growth. But in a beer this big, it couldn't hurt. BTW, there really aren't distinct phases for yeast. The Crabtree Effect states that in the presence of a >.05% glucose solution, fermentation begins immediately.

You can either rack directly on to the slurry or remove the slurry and repitch it. Normally I wouldn't aerate when using a slurry, but given the OG of this batch it couldn't hurt to aerate.

comment Is a yeast starter required when brewing a lager?
A starter is not recommended for dry yeast and can in fact be detrimental.

comment What bourbons work well for flavoring beer?
375 ml. per 5 gal. You want the flavor to be integrated, not scream "bourbon!" at you. To arrive at the amount, I dosed 4 2 oz. samples with different measured amounts of bourbon. After deciding which I preferred, I scaled that amount up to the baatch sizae.

As long as you don't add a huge amount, no problems.

comment Salty Starter. From Gypsum?
That seems like an extremely high Ca and SO4 content. How did you arrive at those figures?
