Looking at style of questions and practising them would help you improve, but the best way to learn them is by far the internet, youtube etc

There is very little you need to know at BMO1,2 level. Just the concept of substitution of 'special' numbers eg 0,1, x=y, x=-y, y=x^2, y=f(x). Some will be useful, some won't, it depends on your equation.
After that, learn about injectivity and surjectivity, and your done up to IMO level. Practice is all you need.

Not really. Practice is key here, there aren't many skills involved, and for the ones that are involved, you should be able to discover most of them.
