1) click on the yellow 2.97 link at the top of the forums for the changes.
2) Not sure how this is coded, penatly wise, however, swords/katanas are not what they wield, if you read the race write-up, they're a hunting people and use spears and shortbows.
3) Not possible due to game mechanics.
4) If you can get all the required feats, I think you can. However, the starting classes are restricted to Druid, Rogue, Ranger, Barbarian, Sorcerer or Bard, so it will be hard. Also, as they're not fond of metals, a sword/katana wielding wemic weaponmaster isn't going to happen. I can see one that wields spears though.
