Unity - 2D physics omissions?

I'm having trouble finding some pretty simple things with the new 2D Unity functions!

Firstly, am I right in thinking that rigidBody2D doesn't have a position variable like it's three-dimensional bigger brother? It was my understanding I should be using the rigidBody positions, not transform.position as this is in FixedUpdate - so what am I supposed to do?

Secondly, I can't access the CircleCollider2D.radius variable despite being listed in the documentation, and above this I can't even access gameOject.circleCollider2D or gameObject.collider2D.circleCollider2D in code (C#).

Am I going mad, Am I missing something, or is Unity missing something? =/

Cheers for any help anyone can give on this, even if it's to confirm something.

if your game object has CircleCollider2d then, you will get circlecollider2d as follow.

1> Declare a variable for CircleCollider2d.

 CircleCollider2d c_collider2d;
  c_collider2d = gameObject.GetComponent<CircleCollider2d>();
  c_collider2d.radius = 1.5f;//set radius value for collider.

RigidBody don't have position values, it always follow the game object where it is attached.
