First learn terminology of 3D, the basic one. Wings 3D is great free app to start with, and get feet wet in 3D. Play around with tools and primitives, get a feel for 3D space. Poles are part of topology, its advanced theme that comes way after you get basic and intermediate level. There is great forum here for Wings 3D, peeps are very helpful. Forget about Maya, Max, etc, those are production apps for professional use, and prices are according to that. As for starting with less "powerful" app, don`t worry about that. Its the artist that make art not the app.

Open your mind and share the knowledge!
