I do my PW with Photoshop and what I mostly use is level and maybe some vibrance adjustment which produces better results than adjusting the saturation.
To make (parts of) the image a little sharper if needed, I use the High Pass filter.
Regarding the bloom, like the previous poster said, duplicate the layer, add some Gaussian blur, maybe adjust brightness and contrast of the blurred image and play around with blending mode (like Overlay, Soft Light, Hard Light etc.) and opacity.
