Hard, plastic toys suitable for babies are good, as are some cat toys. Family members MUST learn that there is a new member under-foot whom they must watch out for. If you must, put up little reminder notes until closing doors becomes habit. Very enticing and very dangerous. Secure to floorboards or up off of the ground.
Bunnies do like to have a spot where they can lie down and nap or be left alone.
Our bunnies like to lie down under coffee tables and chairs where they can survey their world. Eventually she will learn that the boxes outside of her house are just like those inside of her house. Make sure there are plenty of toys available to bunny outside of her house. Putting a bit of hay or a favorite toy at one end of the litter box will encourage its use. This serves only to frighten the bunny and it is NOT the way they learn.
