If an Iceberg is anchored to the bottom of the ocean and NOT floating, would the water level rise as the ice melts?

It shouldn't. I'll answer, as well as add some information. In the North, all of the ice is floating in the Arctic ocean. When the ice melts, it doesn't actually affect the water level. They demonstrated this on a show I watched by having a glass of water filled to the rim with water and some ice cubes. When they returned and the ice had melted, the water level remained the same. So that would be the long answer to your question. It shouldn't make a difference where the ice is when it melts. As a side note; In the South, the Antarctic is is actually on top of land instead of floating. When it melts, it makes the ocean level rise, as everyone knows by following all the global warming news. But its still not good that the ice is melting in the North, it affects the wildlife, such as Polar Bears that need the ice to traverse the area and get fish.

No, the water level would rise when you sank the iceberg, and would sink when it melted. You could demonstrate this with a tall, thin glass, a big ice cube and a soda straw.

Actualy, the level would decrease because frozen water has a volume 4% superior to melted water.
