2003 Taurus 3.0 engine that has a chirping noise coming from a sensor on top of the engine block right in front of the bell housing What is this sensor for and will it hurt to drive it?
That is the CMP or Camshaft Position Sensor. Driving it can and possible WILL hurt the engine eventually. The Squeaking is caused by the gear train being worn out. The CMP in this engine is tied into the oil pump for the vehicle. If the CMP Geartrain was to fail or seize (the reason why its beginning to squeak.) it will stop the oil pump and no oil will be fed to the vehicle. The danger is here, that on this vehicle when the Oil Warning Light comes on, the engine is usually damaged beyond repair. See Related question on how to change your CMP

Can it hurt to drive your car with white smoke coming out of the exhaust pipe?
Yes it will hurt and hurt severely. White smoke is almost always a sign of a blown head gasket or cracked head. Coolant is entering the combustion chamber and is also entering the oil system. You will destroy this engine if you continue to drive it in this condition.
Will it hurt to run regular gas in a Subaru WRX with turbo?
Probably. Most regular gas has an octane rating of about 87. This adequate for an American V-8 engine, but not for a high performance engine. Prior to the introduction of unleaded gas, Regular was usually about 92 octane, and Supreme was between 95 and 98 octane. To get what used to be Regular gas, you have to buy Supreme now. I disagree. The answer is yes or no, depending upon whether Subaru uses a knock sensor on this engine. The knock sensor will modify the timing of the ignition to adjust for regular gas. You would then lose a little horsepower and mileage in exchange for the ability to use the cheaper gas. You can research this, or find an old school mechanic who can hear pinging or preignition, put a gallon of regular into your WRX empty gas tank. If it pings, fill the tank with premium and don't use regular, if it doesn't ping, use whatever gas gives you the price - mileage - performance compromise you want. You can mix portions of tankfuls and the knock sensor will provide an intermediate timing solution.
