Blue loctite can't hurt in this situation.
If you have the bolt size, bolt quality and thread pitch, there are generic values for bolt tightening torques.

my key concern is not to over tighten or under tighten.... given additional weight of the blower and bracket, length and thickness of the bolts I'm guessing Tq would need to be significant.

Guido is correct on this.
Any particular bolt diameter, grade of bolt and thread pitch has a max. torque value.
The fact that you are hanging more weight on a particular bolt has nothing to do with its torque capacity. More related to shear capacity of the bolt that hopefully ESS has taken into account by supplying a stronger tensile strength bolt, if they deemed necessary.
Add some Loctite, torque to TIS spec and enjoy the car.
As far as the brace idea goes, my VF blower plate has a brace added, likely for that reason. Might be worth looking into that.
