What topics of math needed to understand Both theories of Relativity ?

Special theory of relativity !?
General theory of relativity ?

What about M-theory or membrane theory or string theory ?
What topics of math I should be good at ?

To understand the theories, you first need to handle some basic algebra and linear algebra (working with matrices). Once you can handle that, it's a quick jump to tensors, which are a way of shortening a lot of the mathematics involved. Once one gets a handle of a couple of rules, working with tensors can be pretty striaghtforward. Tensor albegra provides the basics of the system in which one will then do calculus.

So you need:
algebra,
linear algbra,
tensor algebra,
calculus

You'll probably have to pick up a little geometry, but you are likely to learn enough learning the above areas.

If you'd like to really, really get deep into the theory, you have to understand some of group theory and more advanced calculus in order to look at manifolds and gauge invariance.
