Your Answer for Question 1:
the virtual address is an address that the CPU produce that is used to access the physical address which locates an actual location in memory.  to get a PA from a VA, you need to map the virtual memory pages to a location in the main memory, which is called memory mapping.

Your Answer for Question 2:
fixed sized blocks make it easier for the operating system to protect its blocks from user programs and thus increases the efficiency of implementing pages.  bigger chunks are good because they can store more different addresses so your virtual memory is larger than your physical memory but smaller chunks are good because they increase performance.
