I'd just follow the structure of the existing EN/JP wikis, all the info is really already out there.
If you can't read the Japanese ones, you can run them through Google Translate or use a plug-in such as Rikaichan to understand it.
You don't need to translate the content, but just having a barebones structure would already be useful and that can be done without knowing any Japanese.
And you're right, wikidot does look a lot cleaner. If you prefer that site and are willing to spend time on building something up, you're free to give it a try, or discuss with others to work together.
It's not really a competition after all, but a joint public service.
It's really up to you guys though, like I said before, it's the players that will end up using it.
