The schools versus meets debate is partially answered by the way in which you learn. Seeing someone performing a task at a meet and then trying to replicate it is one approach but it can be quite frustrating as the person demonstrating makes it look all too easy and, of course, they're not on hand to give you some guidance as they would be on a course. Learning and then practising off Ray Mears's DVDs does fall into that category to a certain degree, the advantage being you can actually replay it any number of times - something you can't with a demo.. However, a school can give you a few basic skills on which you can build.
I've heard great things about Woodsmoke, which is relatively local to you but you might find some value in travelling farther afield. The skills remain pretty much the same but the environment is different. To that end, Bushcraft Expeditions run very good courses as does John Rhyder at Woodcraft School; the former is in the south-west, the latter in the woods of West Sussex.
That said, since you'll be practising your skills closer to home, going to local meets will be a real boon as you'll meet like-minded folk in your area, many of whom will be happy to share their experience with you.
Whatever you do, have fun!
