User:Emptylord/common.js/levelselect.js is where you can find the javascript for the level selector, which you then import into the common.js. The only reason it's in my userspace is so I can maintain it without being an admin, which has proved useful - but you can just stick it in the common.js if you wanted without importing it from elsewhere.

Abilities stats are from a very convoluted system. Template:Data Aatrox and Template:Champion_info/var might be the bits you're missing, if you're trying to understand it.
