The thread by career girl 'A question for the professionals' is at this immediate time, one above yours (it is a sticky). It is extremely informative and you should read it.
I would also suggest reading the 'Do you really want to do this' which is also in the Professional Pilot Training Forum by deathcruzer (still at bottom of first page). It is long but I think essential reading for anyone wanting to go down this road for a future career.
Hopefully these two threads will help you with your research into the start of a great future. Enjoy
By the way I went down the integrated route and found that having a PPL was no great advantage. I would suggest however, that if you haven't already tried it, get down to your local flying club and get a couple of trial lessons/flights to see if you actually like flying enough for the tough but fun time ahead.
