The quoted information above is a great source. I would go there to get a better grasp on electrochem.
For a quick answer (but you should read that page) is that it is possible a mistake in their writings.
Both of those answers are correct.
For question 1 - in the way the equation is written you are forced to calculate the E standard in the forward direction. Therefore, cathode - anode is 0.34 - (+1.36)
For question 2 - it does not provide you with an equation so you are forced to find the most positive E standard. 0.337 - (-0.763)
My advice is understand the equation is Cathode - Anode. Keep your signs how they are presented and plug it into the equation. Maybe they have the addition to skip a step under certain circumstances? Anyways, read the quoted text above.
Good luck
