Actually, I knew some of that, especially the parts about the columns being taller and not standing straight. In the actual one, they're also not spaced evenly and taper funny (called entasis). I didn't know about the roof, as the only image I've got is of the real parthenon in Athens, with only part of the roof still standing. But I'm only basing it loosely on the parthenon, so I'm not trying to recreate it exactly. Thanks for the help, though. Some of that stuff would be really tough to accomplish, or I'd try it.
