That's a good route from CF3, but add Grand Teton since you're already there.
The Grand Canyon trip has lots of possibilities as well. Pick 2 routes
1) Taos, Santa Fe, ABQ, Petrified Forest
2) Zion, Bryce, Cap Reef, Canyonlands, Arches, Moab, and plenty of stops off I70 through CO
3) Monument Valley, Mesa Verde, Durango, Great Sand Dunes, Pikes Peak
