More Shields on ICSP

Hi,

I plan to use an Arduino Shield an SD with a XBee Wireless, and Ethernet Shield, it is possible to solder pins on Ethernet Shield in ICSP?

Sure it is, you just have to get the correct connectors. You can use ones for a prototype shield and cut them after 3 pins, two of such together should work then. Keep in mind that the SS pin for SD cards is usually on pin 4 and every SD card socket has to have it's own SS pin.

The only thing I have to do is just solder over the 6-pin ICSP and is ready to run?

Another question, the Arduino MEGA has three serial ports, it is possible to obtain the output of these three ports from the USB port? Or just a serial 1?

Have you read my whole answer? With that connection you have MISO, MOSI, SCK, RESET, Vcc and GND. These are usable by multiple devices but the SS (Slave Select) pin is necessary for SPI too, so you have to take care for that.

Another doubt, the Arduino MEGA has three serial ports, it is possible to obtain the output of these three ports from the USB port? Or just a serial 1?

I don't know what you mean with that. Using the other serials over your USB connection (so seeing multiple COM ports on your PC)? This is not possible, only Serial0 is connected to the ATmega16U2 which is handling the USB connection.

I am now using the other to the Xbee Shield, which does not use any common pin. If I have understood is not necessary to cut the pin 4 of the XBee Shield, because this is not going to use, right?

Since I can only use the serial port 0 for USB Arduino MEGA, it is possible to use a FTDI Basic Programmer, so to read the serial port 1?

I never tried, but I believe this to be right.

This is correct, but I think you didn't cross the RX/TX lines. This depends on the type of FTDI you used.
