Your Answer for Question 1:
Spatial locality: If you're cooking some sort of themed meal (all fruits for example), when you find one fruit at the supermarket, you'll probably find other fruits that you may need nearby.

Temporal locality: You plan to make several different dishes, but you're focusing on just one recipe right now. So you would most likely refer to the current recipe that you're working on now sooner than you would another different recipe.

Your Answer for Question 2:
We use that particular set of bits because they all map to certain location on the cache. We choose that set of bits because it fits with the equation for finding the mapping, which is (Block address)mod(Number of cache blocks in the cache).

We use the low-order bits to determine cache location because if we used the high-order bits, we would be basically mapping a bunch of bits that near to each other to a location (since we use the most significant bits). However, we handly spatial locality in a different way, so doing this way does not provide any speed bonuses.
