Do I need a spec and bump map for this model?

Acknowledgemets:

In case I forgot to mention it, I want to thank Kurt B. for this tutorial and JrWho for inspiring me to work through uv unwrapping and texturing my first model ever. I learned a ton by following his awesome thread on this Assault Mech tutorial and finally a big thanks to the SimplyMaya community for your feed back and support on all my projects here and SimplyMaya for creating such a great place to share ideas and to learn!
