mike although it might be hard right now, work a little longer until you've got cost of training and living expenses plus a little extra for the job search covered. Shouldn't take too long in IT, and then you can go and train without money worries weighing on you, or, if push comes to shove, even interrupting your training.
You need to consider that loans without the security of a full time job are hard to come by these days (or the bank might simply call it in once you quit your job, they're very risk-adverse at the moment), and you will be sitting on that loan for years as you won't have disposable income to pay it back out of for the first few years..
I have seen too many eager student pilots who had to stop start their training to go back to making money, which in the end just costs time and money because you take two steps forward and one back in your flying progress, especially when it comes to instrument/instructor ratings and other advanced stuff.
In terms of timing, the economy (and the pilot market on the back of that, probably with quite considerable delay to work off the pilot supply surplus) will take at least a year to recover, so if working and training might take you well into next year, you might just find that this slots you slap bang into the next market upturn.. fingers crossed
