dear friend-it sounds like you are having a circulation problem,when the engine has reached normal working temp feel the two radiator hoses they should be the same heat,also check the water pump to see if the impeller is not loose,it is not to say that the radiator is clean after a flush,it must be opened to clean.

Probably the start of a head gasket breech. You can buy a block tester at your local parts store for thirty to forty dollars. Follow the insructions in the box, and it will detect exhaust gasses in your coolant. this is a pretty sure way to detect a combustion to cooling system breech. The cat converter may be masking the white smoke from the coolant once it reaches temp.

The best advice I can give you is to get the Haynes or Chilton's repair manual on your vehicle so you have step by step instructions and diagrams to follow. I say this because there are a lot of items that have to come off and go back in a specific order and you have to set the engine to #1 TDC and the manual will have instructions on how to do this. Failing to do so will cause your timing to be off and the engine to not run properly. The manual will also tell you and show you pictures of how to properly line the cam and crank shaft timing marks up so the timing is correct. The space available for a response is not sufficient to explain all of these steps.

The electric fan is controled by the on board computer in your car and it is not important weather it came on when you started your car or not.What is important is that it comes on when the computer commands it to do so. Has the car been overheating or anything? When the engine reaches a Predetermined temperature in the computers programing, the computer well turn the fan on.If the fan never comes on any more and the engine is overheating then let me know and I will assist you with the problem. Good Luck and have a good XMASS.

Well obviously check the fluid levels first then realistically the only thing you can do as a DIY job would be to get behind each wheel and see if you can locate the wiring to the Wheel sensors. Ensure all these are tight and dry (inside and out). If that don't work I think you will need to have the codes read by a garage so you can determine which part of the system is causing the error.
