Use of Ethernet Shield for Arduino - W5200, SKU:DFR0272

I am trying to use The W5200 Ethernet shield with ARDUINO UNO. I have a couple of questions:
1) Are the pins definitions in the SERVER sketch mentioned in the WIKI page relevant to UNO or only to MEGA?
2) Are these definitions relevant only to thisWEB SERVER sketch or for to any Ethernet related sketche using this DFROBOT Ethernet shield?
3) If they are relevant to any Ethernet related sketch using this shield why are they not included within the Ethernet library?
Thank you
Mike
