Probably the first method, read till I get a new line, then parse the whole thing.

Something like this, then:

char buffer[40]; // Hold a whole record (may be larger than needed
byte index;

void loop()
{
   dataFile = SD.open("data.txt", FILE_READ);
   if (dataFile)
   {
      index = 0;
      buffer[index] = '\0';

      while (dataFile.available())
      {
         c = dataFile.read();
         if(c == '\n' || c == '\r')
         {
            parseBuffer();
            index = 0;
            buffer[index] = '\0';
         }
         else if(index < 39)
         {
            buffer[index++} = c;
            buffer[index] = '\0';
         }
      }
   }
}

void parseBuffer()
{
   if(strlen(buffer) > 0)
   {
       int vals[] = {0,0,0,0,0};
       byte index = 0;
       char *token = strtok(buffer, ",");
       while(token)
       {
          vals[index] = atoi(token);
          token = strtok(NULL, ",");
       }

       // Use the values here...
   }
}
