1) You can use ETTL with not troubles, like stated beforehand it sends out a preflash to properly expose.

2) The external exposure metering is basically like an "Auto" mode on a manual flash. It will try to decide what to set the flash at itself. It does not refer to the camera at all.

3) I too use a +2/3 stop setting while bouncing.
