1. The Ricoh has a leaf shutter. If you want a Fuji with a leaf shutter, the X100T can sync all the way to 1/4000th depending on aperture.
2. I agree. I'd actually prefer a shortcut similar to the card formatting one. Perhaps hold down the Playback button for a few seconds and depress the scroll wheel, etc.
Styled and shot these images with Jessica, who you MIGHT recognize from Asia's Next Top Model (if you watch that sort of thing) which is airing right now.X-Pro2, 56mm, 35mm f/1.4, 16mm f/1.4. Natural light, no modifiers.
