There are pros and cons to doing it either way. I did uni first then flight training. In my case i find that I'm a lttle older than other guys with the same hrs so that was one disadvantage. At the same time though I met some great contacts at uni and had a lot of people give me the real story about the aviation industry rather than the sugar coated version that the flight schools sell.
If I were in your shoes? Try for every possible cadetship/scolarship there is- then the armed forces (your government will be spending like no other on defence) if neither of these work College then flying. Why College and THEN flying? Because in your country a degree is neccesary to gain entry into an airline. In my country its worth..well...umm. I'll get back to you on that one.
