I disagree with Ghengis regarding the military route. To join any branch of the Armed Forces you need to demonstrate your motivation to be an officer first (Army Air Corps excepted) and pilot second. If you think the RAF is a short cut to civil aviation I think you'll find that the Officer and Aircrews Selection Centre will sniff you out. Join the Armed Forces by all means but only if that's truly where your heart lies.
Clive Hughes book, Guide to Becoming a Professional Pilot, is an excellent book and although not very glossy is absolutely invaluable.
Indeed, my flying career started with pprune and Clive Hughes book in the late nineties and has led to the right hand seat of the 747.
My advice would be:
a. Buy the Clive Hughes book.
b. Get your Class 1 medical sorted.
c. Go from there.......
