New to Modding, couple questions...

Ok, so I'd like to change some things around, and am a bit lost on how to do a few things. For instance, I'd like to make an ability similar to spin fist, but for knights, and to have it show the weapon, or to make an archer skill double shot, where it does 2 shots, but dont know how to do this. Also, how to I rename or change class names?
