I may be able to answer #1. If you have a site that is based outside of the US, and a copyright holder accuses you of infringement, the US Attorney General could order your DNS record removed (as well as disable payment processing and advertising services). If you file a counter-notice contesting this action, you implicitly consent to being sued in the US court system. On the flip side, foreign nations may benefit from this legislation, as it will indicate the US is relinquishing their leadership role as custodian of core internet features such as DNS, and may open up opportunities abroad.
