polykarbon has one that's passable, but really what you need is to run a google search on perspective drawing tutorials. (there's tonnes of them). that's all mecha is after all....
for guns, really it's just a case of finding pictures of guns that already exist and maybe modifying them slightly. you can't really be taught how to do that. it's just practise.
