1. I don't think having a registered company is really important. You can get started with Paypal without having a company. Atleast in Vietnam, you can get a bank account by just showing your passport 2. Be on a lookout for local barcamps/tech events.

The best part is that you can easily move to another city if you want to. You just have your backpack to carry around :)
