I can promise you that you are in for a long haul ahead. I'm graduating this week with a degree in Landscape Architecture, which is what a lot of golf course architects study in college and I briefly thought about pursuing a career in it but decided I would stick to playing golf instead. I did take a course on it last semester though.
First thing you have to do is start working for a golf course architect. If you know a golf course architect who will give you a job you are ten way ahead of almost everyone else. If you don't, best case scenerio is that you are digging bunkers with shovel for five bucks an hour. You should apply for Tom Doak's internship program. His website is

Most firms use autocad (nicklaus uses something else) so you need to know how to run that. Knowledge of different grasses is necessary. Do you know how to do a playability analysis?
Each firm is different. It would be very difficult to build a course based soley on a set of plans out of Tom Doak's office. His guys spend a ton of time in the field. Author Hills sends out very detailed plans. I would say that those two are on the opposite ends of the spectrum.
Name recognition is a huge factor in golf course architecture, which is why that starting your own firm in a couple years really isn't a practical goal. Being a chief designer at a bigger firm would be a great accomplishment in 20 years.
I know you said that you are UK based but this is a truely international profession. I have a buddy who works for Author Hills and he is in Europe all the time. Another guy I know is in Costa Rica and Nicarauga all the time.
I hope this helps and I'd be more than happy to answer any more questions you have.
Good luck!
