1) Those are the correct connections and the gauge should report the charge current and voltage.
2) I assume that you meant two 0.02 ohm resistors in parallel. Yes , this is okay.
3) That should be okay.
4) I would check the I2C signals with an Oscilloscope to make sure that they meet spec. Check that you connected to the I2C port on the EV2300. Some people accidentally connect to the SMBus port.
