Regarding the University of Northern Colorado -- I went there a loooong time ago, so things may have changed, but... The best thing about the school was that they did NOT have a grad program in theatre, so undergrads were often getting hands-on experience right off the bat rather than learning it in a classroom while the grad students do the actual shows. They also had a pretty good summer-stock program where I was able to work with Equity actors for the first time in sort of a safe environment. However, they have run into some scandal of late regarding the head of the musical theatre program -- google it, you'll find some horrifyingly yucky stuff - so who knows what will become of the school's reputation or, for that matter, their musical theatre program (another thing that was great about my education -- SMing HUGE scale musicals -- after the shows I did in college, everything else has seemed easy!)
And no, Greeley is no kind of mecca for the arts. I think they have opened up a semi-professional dinner theatre there since I left, but Denver is the closest place for real employment after college, and there never seemed to be enough open jobs in the Denver area for all the skilled graduates the school was turning out. (ScooterSM went there too, at the same time as I did - curious if she agrees with my assessment).
