Funny.........I too became very familiar with some of those stretches of Nevada asphalt recently.
That is a great route as you have it now. US50 is a great road, but can slow you down somewhat in the towns, and while not crowded, will have more traffic and LEO presence than some of the other roads.
375, the E.T. highway is one of my favorite roads of all time. You can easily average 130mph on that road. Just realize fuel mileage and range will go down correspondingly. Don't ask me how I know.
As for Warchild's 157, and Iggy's paltry 152, pfffft! Lame. And that's all I have got to say about that. (Insert faggoty-assed winky smily here)
On your route, the Fallon to Fernley portion will be very slow with a high LEO presence. If it were me, I would avoid that section like the plague and find a an alternate way.
Here are some photos of my time on US50 last September when I headed from Fernley to Ely.
And on US93 west of Caliente.
