Answer: Driving from Las Cruces to Tucson along I-10 is straightforward, but since you want to stop in Tombstone and stay overnight in Sierra Vista, planning your route carefully will help avoid rough roads and steep grades, which is ideal for a family sedan.

Answer: Sierra Vista offers some lovely sunset views without the need for hiking. Since you prefer driving directly to a spot with easy parking and possibly a bench, there are a few places in and near town that are ideal for a relaxing sunset experience.
