Question (sorry if this is a lot): Are the built-in I2C commands supposed to modify the directions for other pins in the same port, possibly to conserve program space? From what I can tell through a couple of my other experiments, it appears that the "ready" pin, which is on the same port as the SDA and SCL pins, is being changed into an output somewhere in one of the I2C commands, so it never gets updated. I'm not entirely sure how this relates to the use of an array variable yet.
