Tension and load are not the same? Tension is just a matter of turning the nipples a certain number of turns. So radial & crossed wheels are typically tensioned at the optimum amount for the rim, 100-120kgf. And load ends up being the same if you've got the same weight on the bike. A 400lb gorilla would load up each spoke in a 32h wheel exactly the same, regardless of lacing pattern.

Yup, both sides does take the torque, even though the right side may face more of it. With crossing on both sides, the right side may take 66% of the torque, while the left side might have 34%. With radial on the left, you'd end up making the right side take up 100% of the torque.
