Eliance My issue is that the Spine/RenderQuad shader is unaffected by lighting
It's unaffected by lighting on purpose, since the original skeleton material which is rendered into the render texture shall cover all lighting. So the correct usage is to setup your original skeleton according to your lighting requirements, render it to the render texture, and then use the unlit Spine/RenderQuad shader to just cover the transparency part.
Eliance Is there an alternate shader I can use?
Of course you could, but why would you want to do that?
