Sounds like you're preparing to exhaust yourself out! That's a lot of places to visit in that time frame. #1 tip is to bring a hat and sunscreen and wear light-colored layers - the weather changes with the sun. Definitely go for the National Park Pass - worth every penny.
When I went last year Glen Canyon was definitely nice, but it's mostly accessible only by boat, as there aren't many roads that skim the sides. The boat tours that take you into the side canyons and Rainbow Bridge take up almost the entire day, so it might be hard to squeeze it in. Thankfully Wahweep (the port / dock) is close to Page, AZ.
I only had a week to run around and my parents don't enjoy hiking, so we were only able to hit the 'touristy' areas. One of the touristy places is Antelope Canyon. It's a nice short tour that can be done in 2-3 hours total, though the tours are run exclusively by the local native Americans. You should definitely bring a tripod, fast wide angle lens, and shoot at noon there, when the sunlight can form heavenly beams straight down its interior. Consider going for the more expensive 'photo tour' if you choose that because otherwise you'll have swamps of tourists in there.
Zion is one of those places I would spend more than a day at if at all possible. I went during monsoon season though (July) which robs you of sunrises (cloudy) and sunsets (storms). Zion's bus tour is quite boring, use the buses only as forms of transportation from one trailhead to another. I would strongly encourage you to visit Kolob Canyon and Cedar Breaks (both N of Zion) if you're looking for less tourist-filled areas. The Mt. Carmel Junction of Highway 9 is also definitely worth traveling trough.
Bryce Canyon is worth hiking down along the rim trails to get a different perspective of the hoodoos. Looking at my shots later on, I realize how flat the place can look taken from a high vantage point looking down on the spires, especially in mid-day light. If you want to save some time, save Bryce for an afternoon tour.
I was only able to spend one day at the south rim of the grand canyon. There were summer wildfires which made sky a bit hazy. I throughly enjoyed watching the sunrise at Desert View. It's pretty quiet on the eastern end of the south rim (no bus tours = far less tourists). I also think the view of the landmarks (like Zoroaster's Temple, the colorado river, etc) is nicely arranged there. If you have a chance, the North Rim gets you more dramatic views. Check the local weather and road conditions before going there. Vermillion Cliffs is worth a quick stop along the way to the North Rim as well.
Through all this it might be wise to bring a film body for the full frame and wide angle capabilities. Velvia film is still great
