emdiesse,
I meant to ask - have you been on a trial flight yet? Always a good idea and won't cost the earth, unless it gets you completely addicted to the idea of flying! Beware, this is what happened to me.
There's a lot of good information on PPRuNe, so look around. Other things you should consider are doing GAPAN's aptitude assessment and making sure you can get a Class 1 medical. But keep doing more research first as the two of those alone will set you back £500! But both very worthwhile investments.
