Why would you go with a whirlybird instead of a ridge vent?

I put a couple of them on the roof of my shop about 15 years ago. One finally fell apart, and the other one is squeaking and will have to be replaced. Most of the new ones have a plastic top that won't last long in the New Mexico sun.
I haven't worked with a used column, but yes, twisting it around will get the correct angle. WD-40 isn't a great lube. There are others with some penetrating oil properties like 'PB Blaster' that work better in my opinion.
Don't make it too loose. I wonder if the wind can make the joints turn if resistance is too low? I don't know, I haven't had that problem.
