Ethernet shield Coding

Try this test code. It uses dhcp to get an ip and the other network stuff. If you don't understand the results, post them here and I'll see if I can help you.

#include <SPI.h>
#include <Ethernet.h>

byte mac[] = {  0x00, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

void setup() {
  Serial.begin(9600);

  // disable SD SPI
  pinMode(4,OUTPUT);
  digitalWrite(4,HIGH);

  Serial.print(F("Starting ethernet..."));
  if(!Ethernet.begin(mac)) Serial.println(F("failed"));
  else {
      Serial.print(F("IP: "));
      Serial.println(Ethernet.localIP());
      Serial.print(F("Subnet: "));
      Serial.println(Ethernet.subnetMask());
      Serial.print(F("Gateway: "));
      Serial.println(Ethernet.gatewayIP());
      Serial.print(F("DNS server: "));
      Serial.println(Ethernet.dnsServerIP());
}

void loop() {
}

edit: My bad. I forgot the includes. I added them.
