I believe pppd will look for a script /etc/ppp/ip-up
The IP addresses are among the arguments passed to that script.
(man pppd for the rest).

Well, that's a little bit roundabout.
if [ -f /var/run/ppp0/pid ] ; then
kill -SIGNAL `cat /var/run/ppp0.pid`
else
echo PPPd does not seem to be running
fi
might be more "usually worded". Subsitute the signal of your
choice for "SIGNAL" there. Likely choices are -INT -TERM and -HUP
(See man pppd for details.)

No, pppd catches these signals and goes through the appropriate
line negotiations for a clean shutdown.

At some point, pppd will call /etc/ppp/ip-down, after it's been HUPped
or whatever.You can get fancy in there, although there really isn't
much to do in the usual case. Clean up any special routes, maybe.
Some kind of special purpose modem reset, accounting, whatever.
