Reply to comment by foootrest in How can I remove a headless screw from a shower valve? by foootrest
In order to remove the stem, you shouldn't have to come from behind. There should be a bonnet that holds the stem onto the valve body so that it can be replaced.
So either the valve stem screws in or there is a bonnet that screws over the stem to hold it in.
Take a picture of the top of the valve.

That threaded plastic sleeve will unscrew to reveal the stem body. Remove and replace for easiest fix.

That looks a lot like this one:

In your first picture I think I see your packing nut as the gray thing behind the stem.
Either way, there should be something to unscrew from the front and remove in order to replace that stem body.
In order to do that, turn OFF the water and then OPEN the shower/tub water flow. What you are doing there is removing the pressure. That body is under 60psi (water pressure) so you wouldn't be able to unscrew anything without first relieving the pressure.
Then you can goto your local home improvement store and hopefully find a replacement.
