Earth.
It is called "reference frame"; and yes, that's the basic idea - related to what will you measure movement.
It certainly is necessary. Sometimes it may be implied - for example, in practice, quite often planet Earth is used as a frame of reference. But whether it is implied, or explicitly stated, you always need a frame of reference to describe motion, or position.
The most common frame of reference is the observer himself and, by extension, the room, lab, neighborhood, or environment in which he feels himself to be at rest.

No, an inertial reference frame is not an absolute reference frame. It is a frame of reference in which an object either remains at rest or moves with constant velocity in a straight line, but it is not considered absolute as its motion can be affected by external forces.
Motion is relative to an observer's frame of Reference.
