Drew,
it won't fix the surge through your network cables, but that didn't come from the lighting directly. That came from a component on your network getting fried and passing the voltage though the network cables. Unless you happen to have network cables running outside that were hit by a strike, which I suspect isn't the case since you didn't mention burning building and such.
Suppressing the surge at the panel will REALLY limit anything beyond that.
POTS lines on the other hand, those run on poles and such and should have a suppressor inline. You can get those or buy power strips with them integrated.
