Airlines And Their Requirements

I have been planning a flying career for quite a while and have been consistently researching ways to do my dream job.

While researching flying schools and which one to choose(in Canada, US or Europe[where I am currently]), I have also read various things about different airlines and what they require(American and Canadian nonetheless). They seem to want a lot of HOURS (obviously!), some sort of university/college degree (to show that you are smart and can do theory) and what else?

1)Do Airlines really look how recognized/good your flight school is where you completed your training and the where you acquired your degree(as well as the marks)? How important is this compared to how many hours you have?
I currently have the option to attend colleges/flight schools in US, Canada, Greece, Serbia and Montenegro, Croatia, possibly other Eastern or Western European schools. Should I go back home to Canada and sign up to a flying program which would be cheap(cuz I am at home) or should I attend a good flying school in Florida or England? I am stuck with this decision right now.

2)Do they really care how many languages you speak? I am fluent in Serbian/Croatian, English and I am going to learn Greek since I moved to Greece. I also hope to learn more languages in the future since I can babble on quite a few others(Latin and Slavic languages).

3)Is fitness/health also important when they evaulate you?

4)What else do they look at?
