What a little teeny tiny cutie! I know what you mean...the bowl would probably be bigger than she is. Her ears will be short enough when she's a puppy that you shouldn't have any problem. I used cat bowls for mine at first since they were smaller.
You probably shouldn't leave her with any plush toys. She could chew them up and ingest the stuffing. Learned that one the hard way...came home to Jake in his x-pen with white stuffing everywhere. Thankfully he hadn't appeared to have eaten any of it...just made a mess. Kongs are great as are any other sturdy toys. The plush toys are fine as long as your are home to supervise.
I'm sure you'll get lots more suggestions.
