I have some questions, I couldn't find a 'weapon editing' tutorial so don't get mad

I want to create weapons and I assume it can be done the same way as player models -the animation.
Maya is my tool of choice, I also have a smd exporter used to hl2. My question is, what do I do with the textures, should I export them with the smd or should I save em separately?
If there is a specialized weapon tutorial, please tell me
I'm not a noob to modelling, but I don't know the least about exporting or animation.
