I suspect that, instead of using /etc/init.d/networking restart, I should
probably just use 'ifup ppp0'. This means that I target the ppp interface
specifically instead of bringing down the entire list of interfaces on the
router (and killing, let's say, DHCP addresses).
Another thing I might be able to do is to NOT check if the connection is up or
down, but to run 'ifup ppp0' every fifteen minutes. Would there be adverse
effects in doing this?

This is what the "normal" situation for ppp0 going down and up looks like if I
do it on demand.

From the log output it seems that the system stops trying to bring up the
interfaces.

My modem is a GNet BB0050 modem.
My ISP is Golden Triangle -- golden.net
I did not receive any specific instructions for setup: it was basically,
"Install the Enternet 300 software, add your username and password, and then
connect." Is there any setup instructions that you were thinking of?
