hi there mate welcome to the world of trials biking.. what you need to learn first is how to balance on your bike and where the balance point is, and then once you have learnt this then you need to master the forward hop. Then once you have got that, then all you need to do is start to try gaps not to big to start with and then work your way up to the big sturth. Also you could start to some drops if you wanted to. Like i said once you have got the forward hop then your away. good luck in trials biking. later.
