Don't know if you've picked a hotel, but Loew's Ventana Canyon is a nice place to stay, and rates are pretty reasonable in the Summer. It's hard to drive to all the distances down in So AZ, but Loew's puts you up on the hill where Sunrise is the main street, and that can take you to Bisbee Breakfast club for a decent breakfast,and is also close to Sabino Canyon where you can walk, hike, or take a tram up into the hills. There's also an El Charro down off Skyline which usually isn't as busy (or quite as cool) as the one off of Court st, downtown. Chicken tortilla soup is great, so is the 3-tamale plate. Margaritas, average.
Also puts you close to Mt Lemmon, which is a nice visit. Although, if you don't already hate cyclists, you will by the time you travel up and back.
Bisbee has the mine as mentioned, The Copper Queen is pretty much the best restaurant, although there are some slightly up the hill (Cafe Roka?) within walking distance by all the antique stores that are getting popular, haven't tried. Some really decent galleries along the main drag downtown, too.
You'll drive right through Tombstone on the way to Bisbee, haven't been there in years but they used to have some pretty cool exhibits, Bird Cage, Museums. One of them had a delightfully tacky little diorama and film narrated by Vincent Price showing their history. Kind'a cool.
