Questions! My greater hose blew but the car didn't overheat

My car is a 2000 323i manual. I was sitting in traffic in Alabama (Iive in Georgia) and then had huge plume of coolant come out, it took me about 10-15 seconds and a 50-100 ft drive before I could get to a parking lot, I knew if I saw the temp rise at all I was going to just shut it off and sit there. But it didn't. I replaced the hose and the coolant and the engine cranked right up. I have had no coolant leak or issue with temperature since this happened on Saturday. The car still feels strong.



After graduating from the e36 to the e46 I have been deathly afraid of overheating due to the aluminum block. So I guess I was wondering if the e46 geniuses would school me on the finer points of the cooling system.



Some questions I have:

1. At what temperature can damage begin to occur to the head or block? And what does this equate to on the temp gauge.

2. Is it likely that head gasket will go before the block/head.

3. When is the electric fan supposed to be on. (Does it turn off after you start driving?)

4. If a leak gets in the system, can the car try to close off things, like the heater valve, in order to try to keep coolant?
