InnerSS map: this shows a zoom on the inner solar system, and the solid lines show ten-day tracks for each of the bodies.

During totality you get to see the inner solar system in its entirety for just a brief moment. Here's a star chart so you can familiarize yourself with the eclipsed sky and prepare where to look for what so you don't fumble in stupid awe at the time.
In Idaho (where I'll be) the Sun will be SE by E. Facing that direction:
Mercury will be just below the eclipse, and
Mars will be just above the eclipse (if it's not too dim to see, does it look orange?), and
Venus higher up, above Mars.
Not sure if you'll see Regulus (a bright star), but here's an interesting note: a very similar eclipse configuration in 1914 seen from Crimea allowed astronomers to measure the offset of Regulus's position, thus confirming a prediction of relativity's model that there's a bending of space by gravity (the Sun's gravity in this case).
Jupiter may be just rising. It's very bright, and may very well be visible at eclipse. We are moving away from it.

Relative to the Sun, Mercury is moving upwards and will pass to the right of the Sun (inferior conjunction on the 26th). If it passed in front of the Sun, we'd have a "transit of Mercury."
Mars is moving upward as we catch up to it on the inside track. We lap Mars (opposition) is a year away. On the map, it shows Mars moving down. It really is, but more slowly than the Sun. So it is increasing separation and is why I said "up" earlier.
Venus is decently far from the Sun, but is closing in on it - greatest western elongation was over a month ago. It is moving away from us and down on its way to the far side of the Sun in January (superior conjunction).
The winter hexagon will be high up in the southwest, so look for lots of bright stars. Sirius is the brightest star (next to the Sun) in the sky. It'll be about halfway up the sky just right of south.
