Knock on wood in case I do something this bone-headed myself, but...

You ARE a dumb ass for letting this happen. Learning how to check oil is pretty basic maintenance, even my little sister can handle it...

Anyways, you might've gotten lucky... it could well be that overfilling the oil let the positive crankcase ventilation system suck oil out of the crankcase (instead of nasty fumes) and into the intake manifold. You then burned the oil, which fouled your plugs (at least #4). If you're REALLY lucky then maybe you didn't do any permanent damage (plugs should self-clean) and the car's fine... You didn't mention how it runs now with the proper oil level.
Otherwise, sky's the limit. Fluids don't compress like air does and you could've easily bent rods or blown seals, either way the motor'll be due for a tearing down...
You might get a compression check to check for bent rods or whatever, and you should keep an eye on the water and oil to make sure there's none of the one in the other or vice versa.
