No, you wont. The PCM uses EEPROM memory and will *never* ever EVER erase itself unless done through an unsuccessful flash attempt.

(It's the same concept as your computer's BIOS)

No you will not. ECU memory is non volatile.

If you hook it back up wrong you might mess up the ecu, but that might not even do it

If you hook it up wrong and it kills the fuses, you may have more issues to worry about than just "messing up" the PCM depending on how much voltage actually transferred. =)

Its 2 wires.. It does not take a rocket scientist.. Although, I did see a "tech" at PepBoys mess it up on a customers car while I was having my rotors machined...
