Nursing job advice

Hi all,
I am currently working as a Full time Registered Practical Nurse (RPN) in Ontario, Canada, Long term care (3 years experience). I am planning to move to Colorado, in next few months. My husband got a job in Col. university. I prefer to go back to school if I have to upgrade in to RN or BSC. If anybody knows the precess please let me know. I have twin boys age 12. They are in gifted program in ON. What is the best place to live close to university. School is the priority.
Thanks
