I2C on MCF51 w/ processor expert

I am trying to interface with an SRF08 sonar using processor expert with the MCF51QE128. I have a couple questions:

1) Do I need to attach pull-up resistors to the I2C bus, or are these integrated onto the board?

2) I only get ERR_BUSY when I try to sendChar to my device (I already used selectSlave() to select the proper address).

Does anyone have any experience with this device or getting I2C to work on MCF51?
