OK, recognizing that I'm trying to learn something here without having
done any homework ahead of time, I have my next question...

I grabbed the 2N3904.mod model from Stuart's tarball, tossed in th the
models directory, reran the netlist, and now when I invoke ngspice, I
get:

Warning -- Level not specified on line "(is=1e-14 vaf=100   bf=300
ikf=0.4 xtb=1.5 br=4   cjc=4e-12  cje=8e-12 rb=20 rc=0.1 re=0.1
tr=250e-9  tf=350e-12 itf=1 vtf=2 xtf=3 vceo=40 icrating=200m
mfg=philips)"
Using level 1.
Error on line 9 : .model 2n3904 npn(is=1e-14 vaf=100   bf=300 ikf=0.4

       unrecognized parameter (vceo) - ignored

       unrecognized parameter (40) - ignored

       unrecognized parameter (icrating) - ignored

       unrecognized parameter (200m) - ignored

       unrecognized parameter (mfg) - ignored

       unrecognized parameter (philips) - ignored

Should I be worried?
Should I expect more out of the simulation than this?
