Let's start with the background image. Fill the layer with solid color...

... double click on layer to open its blending options, add gradient (overay) and a bit of inner glow (black, overlay).

To make this background look like a wall, I took the real photo of a wall (taken by me some time ago), turned it to grayscale (Ctrl-Shift-D) and sharpened the wall texture by increasing image contrast.

then I pasted this image to our file and set its blend mode to soft light.
