First of all, did you have a default route set before you
connected to the Internet? If yes, then ppp shouldn't have
added/substituted the default route unless you explicitly said
so in its configuration.
Ok, that being ruled out, I usually don't use names when I'm
messing with my routing needs. If I'm doing something at this
level, I don't use higher level network services and thus, I
just use IP addresses.

Yes, assigning a higher metric to your gateway route through
you PPP link than through your firewall box would do the job,
at least in principle.

That being truncated is just a matter of formatting of the
output of route. BTW, again, I usually use the "-n" switch
with route or ip (a better program to deal with routing
matters).
