Get your degree first. There's plenty of jobs out there and trying to finish school while working as a regional pilot full time is very difficult, especially during the first few years.
Major in something other than aviation too... it's fine to have an aviation degree, but such a degree is totally worthless if you ever decide to leave the field or want to try something new. Try something like aviation management or business, that way it ties into two fields. I wish I had done that- I'm going back to school now for an MBA, simply because my BS in Aeronautics is of no value anymore...
