Can not apply brush stroke to shape drawn with a pen, or edit a path drawn with a pen at all.

I am having trouble a applying  a BRUSH stroke to a shape path rather than a simple basic line. I want it to be a unique line unlike the simple or dotted line options photoshop is forcing me to choose from when drawing a shape. "Stroke path" is grayed out after rightcliking the shape path.

I can only apply a brush stroke via right click "stroke path" when drawing a "path" vs a "shape" . But then... the path is completely un editable from there on out. What I first define it as and where the path is is then completly cooked in. I can niether change the brush type or size or even where the anchor points of the path should be... Or rather I can select the anchor points and move them wherever, but the characteristics applied to the path and the path its self WILL NOT change or follow... that editing capability is only possible when drawing a shape...
Is there something I am missing? Why is the Pen/path/shape tool so needlessly over complicated.
