Quote - So, obviously I need to redo my render.  Suggestions?  What should I do so I don't get all those bright thingies.  

My humble suggestion would be to check your specular settings on anything you set to Glossy. Anything over 84 is pretty extreme. I try to hover at 50 or way below. That should help curtail firefly production.

Also your light setup is key with this much Glass (and metal if you set a high polish. 9000-9500 is good for the 'new' look, or 5500-7000 for slightly used. 1500-2000 for well used. Just my personal observations. Experimenting helps you learn!)

Back to lights, depending on what kind of shadows you want thrown, one mesh light inside the cube and scaled to your desire is plenty, or a good starting point. You can always up the power/gain to offset for size for that size scene. Also for the cube itself, you can always set it mildly opaque or even matte translucent and set a textured plane behind anything in the camera view and place light(s) outside the cube. Just remember that each light source in the scene quantifies complexity, i.e. render calculations. Maximizingwhat you can with fewer lights means faster rendering (general rule of thumb).
