You can go any path you want, in the end you will get the same result which are the ratings you need. No one can tell you what route to take, its what is best for you.

There are a lot of threads on different flight schools and that is for you to research. I highly suggest you get a degree before you enter the industry. It is possible for you to get it while working, but might not be the easiest. (From what I have seen, people say they are gonna get it and wait around a long time before they actually do, if they even go back). I would not recommend getting a professional pilot degree. If you end losing your medical, you will have a worthless degree and probably large loans to pay off.

If I were in your shoes, I would finish college and fly on the side if you have the opportunity to do so. Get as much done as you can throughout college and then decide on what flight school to go to when you get done. Personally, I got a management degree and went to flight school after college. I also knew it was what I wanted to do before I even went to college. It was fairly cheap for me too since I went to community college first. I got done college with little to no loans.

In the end, its about what will work best for you. As I said, I highly suggest getting a degree before coming into the industry and if you can, fly on the side in college. And it does not matter what you have a degree in, as long as it is a bachelors. If you can stay away from pulling out loans throughout the process, even better.
