Yes and Yes, the setting is assigned at boot time and depends on an
algorithm which you can read about in tuning(7) IIRC.

I would say give it a go and see how it fairs.  Check out sysctl -a for
your current settings and see how it changes when you set MAXUSERS to 0.

Also check out fstat(1) to see what open files you currently have and what
is consuming your file descriptors - perhaps you can cut down the number
of open files.
