Actually I'm pretty sure they are weighted differently.
Nope. The different shapes just show different propertys of the bone. Does not change its weighting.
Stick - This is useful if you want to see behind the bone.
B-Bone (My favorite) - Allows you to see segments.
Envelope - Allows you to use the Envelope (Control amount) around the bone.
And then finally, Octahedron - Is the simple all around bone.
Take my word for it.
Sonethin smells fishy.
I would never. That was in march! From that time I have learned hundreds of new controls and have modeling more then 78 objects. You will improve soon enough.
Anyhow, here is my Tank, I'm thinking of selling it, please criticize it



I'm planning on finding, painting, or asking someone here to paint, a texture for the tank.
