Your Answer for Question 1:
A virtual address is not a physical address in main memory.  It is instead mapped to a physical address which is an actual location in main memory or DRAM.  You can ge t a PA from a VA by looking at page table which is indexed by the page number from the virtual address and contains the corresponding physical page number.

Your Answer for Question 2:
The advantage of fix-sized blocks is that it eliminates the need to find a contiguous block of memory to allocate to a program.  The operating system just needs to find enough pages in main memory.
  Bigger chunks will reduce the rate of misses.  Smaller chunks reduce the miss penalty but not enough to compensate for the latency time for disk access.  Smaller chunks allow virtual addresses to map to more locations in main memory.
