Are you saying that SDA and SCL can be used on almost any ports?? I thought they where dedicated to a specific port each..
Yup, I2C is a bit-banging solution, sorta like SHIFTIN/SHIFTOUT. Remember the wiki post I linked you to.

Just be sure to have the analog turned off on the PIN you choose. MCLR does not work either. Other than that you should be good.
