Your 137 quid would be better off in your pocket for the time being. Read the sticky threads on here, regarding early steps, how to trade. It's all good stuff, warts and all. Ftse beater wrote an excellent piece some time back, and there are many, many, articles and threads to keep you going.
I think I would be correct in saying that there is so much content on these boards that you will be hard pressed to find additional material elsewhere. What you will get and be offered is the dressed up glossy promise of overnight riches/ New trading techniques/previously undiscovered ways of trading from vendors etc etc. Just remember there is nothing new in trading. no matter how glossy it's dressed up.
After you think you have read enough, take your 137 quid, add a bit more to it and start trading. (Demo accounts to start with). That's when you start to really learn some lessons. After a little while you may find that you need additional training. The smaller the amount of people in a group the better (for you), one on one is better imho. Again, the good and the bad trainers have been mentioned on here.
More importantly though. You have to decide what type of trading you want to do. It's no good learning about scalping a market/share etc, if you can't sit in front of a computer all day. And just because forex is a 24 hour market, it doesn't make a lot of sense to open a position in the eur/usa at 11.30pm while everyone is sleeping.
It's a long road. Make sure you have sturdy walking shoes!
