Peds RN needing general travel information

I have 10 years experience as a Certified Pediatric RN. I am in the midwest and would like to start traveling. I am interested in San Diego California . I don't know where to start. I don't do nights. Is this a problem? What are people talking about when they refer to housing taxes? Has anyone ever requested to be put up in a "corporate furnished apartment". I will be taking a leave of absence from my current job. I currently have benefits, but don't don't if the insurances are covered for x months during the leave of absence. What questions should I be asking a travel agency before commiting?
