Flagstaff: Museum of Northern Arizona is excellent for local geology (Grand Canyon vicinity, dinosaurs) and Native American archaeology, arts and crafts, etc www.musnaz.org
Phoenix: The Heard museum (Native American stuff) is absolutely top notch! www.heard.org
And Tucson's Arizona-Sonora Desert Museum if fantastic! www.desertmuseum.org
If I were doing your trip, I'd also catch some caves along the way. In Arizona, that would be Karchner Caverns (you might want to make an advance reservation, however)
