Answer to: iPad 3rd Gen Digitizer the same as 2nd Gen?They appear to be different parts (iPad 2 digitizer, iPad 3 digitizer). That said, I've scrutinized the photos from the iFixit teardowns of both the iPad 2 and iPad 3, and darned if I can see any significant differences. The metal shield around the camera appears to have grown a spring-contact on the iPad 3 to improve contact with whatever it touches, but that looks like it. And it would be very in keeping for Apple to use the same part for both iPad 2 and 3 if they function the same way. The logic boards of each of the two even have their various connectors to the screen and speaker arrays in the same spot. So: inconclusive. Maybe we'll luck out and an iFixit staffer will compare and contrast the parts for us.
Answer to: Where is the internal microphone on the iPad 3?Still behind the iSight camera on the rear panel.

Those aren't security Torx -- there's no center pin. They're just 5-point Torx, branded "Torx Plus". They allow greater torque and lower wear (but mainly exist because the 6-point patent was expiring). They are a bit rarer, thanks to limited licensing, but not a tamper-resistant fastener at all.
