Unfortunately these two pipes are not labeled so I'm not sure where they go.
The valve cover is installed incorrectly. Take out all the screws, remove the valve internals and rotate the cover 180 degrees and re-install. That should fix the valve problem. While you have the valve apart, check the o-ring for any damage as that can cause a leak.
