I don't know if its because of the. 215 update or if its available in stock, but there is an option in the camera app to turn off the shutter sound.
And good luck rooting! Coming from a crackflasher, make sure you read through custom ROM threads before you install! User feedback is important when you get to the level of "omg new rom, flash first, ask questions later."
