The FOV slider can only be moved in pretty large increments (74 down to 45 in one increment), but you can set it to anything you want in the cfg file.
The camera actually tilts when turning (it doesn't "bob"), and the weapon bob option doesn't affect it, only the weapon model. It doesn't look like there are any cfg or console options to disable any of the camera motion. It doesn't bother me, but I think it'd be nice if there was an option to disable it.
