Hi Miha,
Sriram got all the questions covered, just want to clarify a small
detail.

IIRC, even with the camera in M mode, the pre-flash should fire at the first
curtain and then the actual flash will fire at the second curtain, just like
in Av mode. Maybe your shutter speed setting in M mode is too fast to
observe the two flashes, or you're talking about the flash being set to M
mode?
I'm using EOS30 with 420EX, if it matters.
