Difficult to offer advice as IMHO there is no right or wrong answer. You seem to have a great attitude and that is the most important thing. I'm sure you'll be successful whichever route you choose.
One thing to consider is whether to delay your PPL and keep flying gliders. You could then apply for one of the cadet schemes and with your obvious dedication to flying I think you would be at the front of the queue for these. You could then go modular if you didn't get on the Ezy/Virgin/whoever scheme.
