Can anyone tell me what's going on the top left glass area?



Using 0.2.3 with 3DsMax 2014. Here's the setting, Sample Rate, and Noise Level

Check the pillar's metal material, probably the bump map is too small.

This is not fireflies. It is a light sources reflections in the glass.
Regarding the second issue. It happens because of polygon overlapping between the glass and the floor. You have move glass object a bit up or down to avoid overlap.
