Where do I store my dirty laundry and how do I wash my clothes?

This will be different in each homestay. It is important you speak with your host to clarify laundry rules and to avoid any issues. Ask your host where they would prefer you keep your dirty clothes. Some may prefer you keep it in a basket in your room, while others may ask you to place it in a basket elsewhere in the house. Some hosts will ask that you do your own washing and will teach you how to operate the washing machine. Other hosts will prefer to do your washing for you.
