During night on the Moon is there Earth light and Earth phases? I realise that night time on the Moon is two weeks, however I am curious if during the night there, whether or not the Earth reflects light in similar manner to the Moon. 

On the one hand, I know it must (as seen in photographs from astronauts), but what I'm really wanting to know is:

Does the Earth have phases like the Moon and do they work in a similar manner for an observer on the Moon?

I assume the Earth isn't as reflective as the Moon since the Moon is much lighter in colour, however the Earth is also fairly larger, does this make any difference in the amount of light reflected?

Finally, if the Earth does appear in phases, does that mean that the two week long nights on the Moon are sometimes pitch black (new Earth) and sometimes less than pitch black (full Earth)?
From the perspective of the Moon, the Earth exhibits phases just as does the Moon when viewed from the perspective of the Earth. There are however some differences. One difference is that the phase of the Earth at a fixed local lunar time will be pretty much the same from one day to the next. This is a result of the fact that the Moon is tidally locked. Another difference is that earthlight is considerably brighter than moonlight. This is a consequence of the Earth's significantly larger albedo and significantly larger diameter compared to the Moon. A third difference is that except for locations close to ±90° lunar longitude, the Earth doesn't rise and set.

You have this backwards. The Moon is rather dark. It's reflectivity is about that of old asphalt. The Earth is significantly more reflective than is the Moon.

No. This is the first difference between Moon phases and Earth phases. Earth phase on the Moon is a function of lunar longitude and time of lunar day. You won't see a full Earth one night and a new Earth some other night.
