OK, generally speaking, should I sand with or across the joints?

There is no grain direction to joint compound so it doesn't matter.
As you taping skills improve you'll find you'll end up sanding less
and less. I've basically given up sanding - too messy and generally
too annoying. I prefer to follow up with another pass with a wet
sponge.

I'm using a 100 watt flood light with all other lights turned off and
holding it up against the ceiling so it shines across the ceiling. *That
makes the imperfections stand out!

Sure does.
