Why would you wax the handlebar/stem interface? Given that you depend on it not to move, lubricating it sounds like a bad idea to me.
Lubricating the bolts (with grease or something like the Finish Line anti seize) is a good idea, but what's 'assembly paste' in this context? I've only seen that name used for a carbon- specific product.
As for torque, normal sized allen keys are about the right length to apply the right sort of torque to the bolts they fit - snug them up good and tight, without swinging on the key like a gibbon. In the absence of a torque wrench, that'll be good enough.
