set the inertia to 10 or something like that. not sure how you ended up with
0, that's not a valid value. other than that it looks alright. remember that
you need evdev from git, evdev 2.2 doesn't allow it.

not yet, sorry. scroll handling is a bit weird, due to the requirement that
it is converted into button events before posting. the driver has the wheel
axes hardcoded. it'd be possible to add a configuration option for that but
you'd have to write the patch yourself. it's not that hard, but it requires
lots of testing to make sure it doesn't interfere with other button and axis
mappings.
