You don't need to mention all of them in the .fps...texture0 is all you need. Also, you don't need the d2 texture, you can erase it.
I know what the problem is. You need to add a transparent alpha channel to the specular map. If it doesn't have it, the texture will glow in the dark. That's how you can have segments and entities with lights on them; make that section on the alpha channel white and it glows in the dark.
So yeah, just give the specular map a black alpha channel and it should be fine.
A picture says a thousand words.
