You can visit the works of art on the tour in any order you like; it won’t affect the outcome if you do this right. Parking at ASU is always a joy, of course. 
The parking waypoint under additional waypoints is the closest to the initial coordinates. The garage is $3/hour, but is free on weekends. And if you’re willing to walk further, free parking is available in the neighborhoods to the south and west of the campus. An ASU parking map is linked here.
Cache is not at the initial coordinates. To reach the final coordinates, you must answer the question for each waypoint, then fill in the coordinates below. Most of the questions will require a little thought or careful attention (i.e., you really have to LOOK at the work of art). You may need to do some math or look up additional information to get the right answer for a couple of them (a smartphone or tablet would be good to bring along, although ASU also has a library with public computers).
Here’s a link to the ASU Public Art page, and a link to a map of the collection. Not every work of art is included in the tour, and two of the stops, while they qualify as works of art or architecture, are not on the official list, which has not been updated since 2010 (I believe both items have been acquired since then). However, the tour passes close by a number of the other works of art; take a moment to look at them as well. For those interested, three of the artworks on the tour and two artworks that the tour passes close to are also on Waymarking.com, as are several other features of the campus that you may pass. The waypoints are in the order in which I would do them myself as most efficient in terms of time and distance, but you don’t have to follow that. I have not given the titles of the artworks under the waypoints, labelling them simply by letter; you'll find out what you'll be seeing when you get there!
Here are your questions to answer:
A = How many of the beasts here have three feet on the ground?
B = The number of distinct colors seen in this work of art. (Shades of one color do not count as a distinct color.)
C = The Renaissance predecessor of this artwork was sculpted in the years XXXX-XX_X. Give _ its value.
D = Excluding thumbs, what is the number of fully visible fingers on this work of art. In other words, when facing the statue, how many fingers can you see clearly in full outline, with nothing covering them?
E = The square root of the number of panels in one of these works of art.
F = How many letters are in the word displayed here? What language is this? By how many letters shorter is the word in the original language?
When you have all the information, proceed to: N 33° FE.FDA W 111° EE.CBB. The final location has a view of my favorite work of "art" at ASU, although it is not the same kind of art you have been looking at. Enjoy!
There are some features on ASU's campus that may make your GPS signal bounce. I did the walk a few times over and am confident that you can at least see the artwork in question from each set of coordinates, if not be right in front of it. Some works of art are close together, but the questions make it obvious which one you should be looking at.
Ratings (used the Geocaching.com rater):
Difficulty: Some walking, and a time investment of probably at least an hour. It would make a nice evening or weekend stroll. The questions may require some thought and research, but are not unanswerable. The final cache should be pretty easy to locate as there are limited hiding places in the area (and there's a hint). Because of the nature of its location, the cache container is a nano chosen for its ability to blend into its environment.
Terrain: You can stay on sidewalk almost the entire time. You may occasionally need to go up stairs or slopes. For strollers and wheelchairs, there should be ramps available. You may also need to dodge a lot of foot traffic as you move around, depending on the time of day and what day you visit. There are ample sources of food and drink along the tour on weekdays, and at least vending machines and water fountains on weekends. And plenty of benches and shade.
I strongly suggest not doing this late at night because of the setting and the nature of the questions. All the works of art and the final location are available 24/7, but not all are lit up at night.
