UV Unwrap - Object - Select Faces ONLY - and Paint UV I have two part problem.

First:

I have a circle object, you can see the UV in black.
I selected the middle faces as you can see. I UV unwrapped on the selection.
I am paining those faces(selection), as you can see in the UV editor to the right of image.
BUT! There is the same painting over and over in each face on the entire object? That is an unwanted result.
I only want to paint on the selection in the UV editor. Is it a node setup I did wrong? I can't seem to find this particular circumstance.

Second:

Where are the paints? In the center I have stroke and fill, but they don't seem to do anything. No matter what color I choose, it only paints that white-wash/gray color. 



I added this image below (edit): Seems I got the correct Tool-box open. I can paint.
1) You started with a resetted UV mesh (all faces overlapping and occupying all UV space available), then you re-unwrapped part of the mesh. The two unwrapping operation got some overlapping, you can see it if you select all faces. The correct way is to unwrap one time only, then select the faces you want to paint, turn the 3D window into "texture paint" mode, enable the button named "face selection masking for painting" and paint in the 3D window. 

2) The stroke/fill controls you tried to use are referred to the grease pencil only. In the UV/image window, you can acces to the paint controls pressing T, to show all tools tabs on the left of the window.
