Well when you texture the ball, in the attribute editor for the shader, go to extra attributes, and there should be a glow option, click on that to add glow. As far as the glass, it's hard to tell right now because it seems like you're still using default lighting, but they should be reflecting more light off of them, put the specular color up higher, and some more eccentricity maybe. Right now it just looks like a transparent lambert.
