Well, actually Dave, I moved to Santa Fe five years ago from San Diego. Also, my parents had an apple orchard in Camp Verde so we went to the "big" stores in Sedona at least once a week. And even my Mom would tell us stories about being a kid and going to slide rock before most even knew of the place, so it was family tradition.
As far as the $100 pass, unless you live in the area and plan on returning to parks, I would skip that. For instance, if you plan on going to Bandelier, (Which I love, beautiful country and cliff dwellings), the fee is something like $3.00 a car load. If you went to Utah and were going to Bryce Canyon, Zion, drop down back into AZ to the North Rim and into CO to Mesa Verde, then yes, it would probably be worth it. With your itinery, Grand Canyon is the priciest with everything else being much, much, less. (Oh yeah, and about 7 miles north of Santa Fe on Bishops Lodge Road is Shidoni, an outdoor sculpture garden with a huge foundry on the premises and glass blowing artisans, again, it is totally free!)
Hope that helps.... (Oh yes, And my husband said to mention Rio Chama for their Nachos, a huge plate that serves 2 to 3 people for about $11.00), Next door is the Pink Adobe and across the street the oldest church in the US. If you go, make sure to poke your head in the Red Dragon saloon, they have a live tree growing inside through the roof there. Also, some of the residents you may bump into along the way would include, Gene Hackman, Alan Arkin, Ali McGraw, Patrick Swayze, Julia Roberts, Robert Redford....the list goes on and on. The cool thing about Santa Fe is nobody really cares what anyone does so it's considered rather a "safe-haven" for a lot of people.
When does your family plan on leaving, if I may ask? ( I'll let you know of any concerts coming up or live performance and gallery openings as a lot goes on through the summer here.)
