Yes, when z = -pi/2, you're looking at your own planet, dummy. For astronomical art appreciation, I don't really need to look at an ephemeris anymore. I know where the planets are. An ephemeris is really for precision work, like when you need to know Earth's position in heliocentric coordinates so that you can determine the orbit of an asteroid or comet that you're watching.

The best place i found things like that is on www.artcharts.com if you print out the yearly calander it may take awhile to read it.

Find the web site for your nearest planetarium - there should be info about what is visible from your vantage point.
