Arduino Uno+Ethernet shield+Sensors Shield

How are you today hope all is well with you.I am going to work on a project with the following structure Arduino uno +Ethernet shieled+ Sensor shield in the following link http://arduino-info.wikispaces.com/SensorShield

so Please I would like to ask Many questions 1)will it work without problems if i put the Ethernet shield over the uno and put the sensors Shield over the Ethernet shield or i will face troubles.

2)I will use three sensors each sensor works on 5v can the uno provide this volt to them through the sensor shield or i will need a power source for the three sensors .

3)I will Make this system interact with another system that composed from Arduino uno + GSM GPRS Shield(with it's GSM\GPRS Module in the following link http://store.open-electronics.org/GSM_GPRS_GPS_SHIELD) through software serial Is it possible or i will face problems.

If any one have any advice for me I will be grateful.Many Thanks In advance

You don't have to expect problems.

2)I will use three sensors each sensor works on 5v can the uno provide this volt to them through the sensor shield or i will need a power source for the three sensors .

That depends on how much current the sensors draw. The Arduino provides 5V but only a limited current (around 0.4A). Usual sensors don't draw more current but you have to care about that.

3)I will Make this system interact with another system that composed from Arduino uno + GSM GPRS Shield(with it's GSM\GPRS Module in the following link http://store.open-electronics.org/GSM_GPRS_GPS_SHIELD) through software serial Is it possible or i will face problems.

If you connect to that other system by software serial, the GPRS shield is not involved, so I'm ignoring it. SoftwareSerial is valid up to about 38400 baud. If that's enough for your needs, you don't have to face problems.

Many thanks but i have another question can i control the current of 5v out from Uno to the Ethernet Shield to the Sensor Shield

Many thanks but i have another question can i control the current of 5v out from Uno to the Ethernet Shield to the Sensor Shield

No, but that does not make sense IMHO. What do you wanna achieve?
