Ahh I remember my cadet days, when 6 flights looked like loads on your 3822 until you meet an ex military pilot with over 20,000!
Keep working at the cadets, it helped me a lot when getting jobs, infact it gives you really good answers for a lot of the interview questions.
If I were you, I would keep going with the cadets, keeping working hard at school and keeping saving! Not many people can save these days
To answer your questions again with more info:
1) At the moment its looking at about £6,000-£7,000, most people fly from around £105-160 per hour.
2) From looking at the price list of my local school, it's £5,500
3) There are two I think, RVL and Highland Airways. Both are very, very hard to get into.
4) I don't know of many that will pay for all your training without locking you into some sort of a long term contract I'm afraid.
5) Yes. Even some of the flight schools are hard to get into. I believe CTC is something like 6-7% entry rate
