Because you want to interact mid way through, this would need to be several actions.
I'd suggest creating a droplet File > Automate > Create Droplet
. It is basically a shortcut icon you can place on your desktop that runs a PS action. If you create an action droplet for each stage of your process, you can just drag and drop your images onto the droplets without having to manually open them up in Photoshop.
Also, if you upgrade to Creative Cloud, the camera raw filter has a MAJOR upgrade in that you can apply it non destructively as a filter, instead of actually editing your raw file. It also works on non-raw formats, so you have all the camera raw features (exposure, vignetting, saturation etc... ) working on a JPEG for example.
