No. That's one of the properties of gravity ... the work required to go from
one point to another depends only on the difference in height between the
two points, and not on the path. A 'field' in which this is true is called a
'conservative' field. The electrostatic field is another one.
Yes very very slightly.

the job gets easier the higher you lift the object
The potential energy of the book on the shelf is equal to the work done to lift the book to the shelf. This is because the potential energy of an object at a certain height is equivalent to the work done against gravity to lift it to that height.
no
false
no, but the POTENTIAL energy may equal the work done to life the book to the shelf
There is no direct relationship because the potential energy of the book on the shelf is defined relative to an arbitrary base line at which the potential energy would be zero. The work done in raising the book is the increase in the potential energy of book from however much PE it had in its previous location - for example, on a lower shelf.
Yes very very slightly.
You can paint shelf liner but it may not look so good if it starts to lift.

The weight that a mouse can lift will depend on its size. It is estimated that mice can lift things that twice their body weight.
turn off the lift and vent the tank
