A generic will be fine.
why? you're protected by ebay/paypal. I've bought loads of stuff from China without issue, the only thing is you have to be prepared to wait a while for it to arrive.
Yes
Size - usually expressed as e.g. "80 x 80" or "80 mm sq" There are standard sizes - 40mm, 50mm, 60mm, 80mm, 92mm, 120mm, etc.
As you say the fan clips into the top of the heatsink, the depth matters. This is expressed as e.g. "80 x 20 x 25" for an 18mm sq, 25mm tall fan.
Double-check you have the voltage right.
If the replacement comes without the plug on the end, cut the plug off the old one and solder it to the new one's wires.
Yes.
You'll probably find buying a complete replacement heatsink/fan is easier and quicker than faffing around with wires and lubricating bearings.
Yes
That's the right oil to use. 3-in-1 is fine also
Yes, very. Usually it's the label with the maker's name and model number on it. Peel it off (it may well be foil-backed) and you'll either expose the bearing or a hole with a small rubber bung in it that can be prised out to expose the bearing.
Just a couple drops of oil. The original label won't stick back on, just cover the hole with a bit of tape. Electrician's insulating tape is fine. You may need to clean off the surface surrounding the hole with a solvent (lighter fluid, IPA, etc.) before the tape will stick.
Blowing down through the fins
It does matter.
