Finish you college - 4 year degree. Then worry about finishing your ratings. That 4 year degree is a nice thing to have out of the way. Aviation is not going away - you'll be able to complete your flight training after school...
I know everyone is in a rush to get on the line and start flying - but if you have to choose btwn a 4 year degree and flight training. Take the 4 year degree then worry about the ratings...
Maybe not what you wanted to hear but thats the way I see it. I stopped after my PPL - didn't want to keep spending money or tap the GI BILL for flight training. I plan on getting as much education (Masters plus cisco certifications and if i have $$$ left a certified financial planner cert) outside of aviation before i get into pro flying...
Another thing, don't think about this stuff too much - you'll miss out on college life and it can be a lot of fun...
