I don't entirely agree that's a good introduction for someone without
any background knowledge in TCP/IP, but certainly a good resource when
one has some of the basics already.
To answer OP's questions,

Given that you do not already have a reason to do so, I would say not.

A network card (also called an interface) can have both, and they are
not the same address. IPv4 and IPv6 are two different network stacks,
with different addressing, routing, etc.

Yes, for the same reason as above.
Sadly, most of the world is still on IPv4, so until IPv6 is deployed
across the majority of the Internet, then if you're not a large entity,
there's not much reason to use IPv6 other than playing around.
Here's a gentler introduction to IPv6 that might also help:
