Basically, yes, although I build from the source code myself. The feature should be in all builds from 7 August or later. That goes for every CM10 device which has hardware keys, not just the I9100.
It was submitted to CM9 but not in time for the feature freeze for the release candidates. I think it's unlikely to be added now that CM9 development is meant to be just bug fixes.
Glad you like it.
The feature has only been merged in CM10 for a couple of days, so if the build you're running is older then it won't have it. Otherwise it should be in Settings -> System -> Hardware keys.
The
action overflow is the 3-dot software menu button which removes the need for a dedicated menu button. That provides the reason for remapping the menu key to the recent apps switcher (though I can still open the menu with long-press on home, for compatibility with old apps). The back key can't be customised in these settings because of the kill-app feature in the dev options. The search key can if your device has one.
I haven't had any problems with word suggestions showing up while typing, so I don't know what could be causing that.
These are the available custom key actions, by the way:

Ah yea, I think it's just not in my build. I look forward to these features :D
