As far as amount of water in your mortar I was always taught less is better....according to local brickie and concreters.

....I'm no pro tho....

As long as there is no smoke coming out of the cracks during the early stages of a fire, I do not feel that cracks make much difference - and as stated they will be covered with insulation.

On the other hand, if smoke does appear, that's a problem and should be taken care of before getting to the insulation stage.
