Help with Alpha channel and shader nodes in evee

Blender is awesome! Let’s start with that.

Simple question probably made way too difficult is:

Is my node setup correct in this .blend for what I am doing, which is attempting to cause the non alpha channel to emit and bump whilst leaving alpha attached to other color or texture. Any simplification or corrections would be appreciated.

Thanks in advance for any help or insight as to how this is supposed to be done.
