That's supposed to be you being punished for doing something wrong... so you're forced to sit on your knees with arms raised.

Elderine will always be the most crowded place. So you pretty much have a whole map to yourself while out grinding.

House zones are where you can go into your Mushroom house. There is a quest that gives you furniture which can be started at Robin when you're level 10. It requires you to go back and forth from Roumen to Uruga though. At the end of the ordeal you'll receive a skill which will allow you to go inside while within those zones.

@Vivi: You may have to install an East Asian Language Pack if you've tried doing what lvra said.
