Those dots are iterations that still have to be done.
I'm guessing that model, and the other one, have Translucency parameters. Translucency is heavy on the calculations, much like reflective or transparent materials, like glass or mirror. You can see that the reflective surface on the purple and blue frames, as well as the black poster also have the dots. The walls and the bed don't because those are easy calculations.
The right balance between render time and end result is subjective of what the artist desires as his objectives.
My criteria is that I want to make pretty pictures, with good quality, but in a rational time so that I can release a game in months and not in years. Because of that I have to "accept" some decrease in quality in my pictures.
You have to decide what are your criteria. If you don't mind the time then pump up those iterations. My standard iteration number is 5000. Sometimes my pic is done under that number, sometimes I must push it to 10000 or 15000.
