Table travel: Is this range measured from hard stop to hard stop? does This value set the soft limits? How do i set soft limits?

It should be a little less than the absolute travel limits. But only a little, as the machine knows that it will need to decellerate to a stop at that point.

Home switch location:Would someone give me an example on how to set this value?

This might help:

What/where is the machine origin for a 3 axis cnc?

To an extent it doesn't matter, as long is it is a right-handed coordinate system. Typically the G-code origin is somewhere on or in the part, and there are several sets of working coordinate systems (offset from the machine coordinate system) to allow for this.

However, many CAM systems assume that Z = 0 is tool fully up, so you should set Z-max - 0 and Z-min = -250 (or whatever)
The X axis should increase as the tool moves to the right. The Y axis should increase as the tool moves away. If the table moves rather than the spindle, then you still need to look at it from the point of view of spindle relative to work.
