1. Manufacturers don't generally specify a replacement interval for timing chains. They are supposed to last as long as the engine. However, periodic inspections (say every 100K km) are advised to determine if the chain has wear or slack. Some modern cars even have wear/stretch indicators that cause a light to be illuminated on the dashboard.

2. As mentioned above, it should be lifetime with periodic inspections. Checking the vehicle workshop manual would confirm this. 

3. Pretty much all modern petrol engines are interference because manufacturers try to achieve high compression ratios from smaller engines. As a user, it is important to understand that if the car has a timing belt, and if the engine is an interference type, the damage that can be caused if the belt snaps is far greater than on a non-interference type engine. Other than that, it doesn't really matter to a driver.
