You can measure it any way you choose, as long as you make it clear how
YOU are measuring the distance.  If you are following someone else's
specs, you'll need to understand how THEY are measuring it.  There is no
"standard" way.

Take a sheet of paper with at least one straight edge somewhat longer
than the circumference of the tube, and wrap it around the tube so that
it overlaps on top of itself.  Then trace the edge of the paper onto the
tube.  

>3) What sort of glue do you use to attach the secondary end caps?

I don't recommend using glue.  I always secure the end cap disks with
screws.
