I would list the permanent job first, and then list the temp jobs as "Various Temporary Assignments in Kansas City, MO" or something along those lines. Lots of people have more than one job at a time. If you have a good relationship with your contacts at the staffing agencies, ask them if you can use them as references. I work for a staffing service, and it surprises me how few people realize how important references are! Good luck to you!
