Jay,
I only skim read your main post. Before you commit any thing to the industry. Visit your local DAME and get your Class 1 medical out of the way.
If you don't know any, go to the CASA site and look them up.
I'd stick to Australia for the time being. If you get tagged for a cadet scheme, good luck but if you don't, you don't have to spend a small fortune to get a start. GA is still happening and it's a very good place to start for your airline career.
One word of warning, do not come across as a smart arse. At this stage of your life and career, humility with quiet confidence will stand you in far greater stead.
Good luck.
