What size batteries do these toys need? I don't see info anywhere...

You need 2 AA batteries. They last a reasonably long time.

Would this be a good starter set for a very bright nine year old? Can he make his own designs with this set? Will it teach him about engineering?

Yes. My kids had a great time.will teach planning, visualization and engineering skills. May need some adult supervision since some of the directions are very detailed

I'd like to get this but I will also need to get a container to keep all the parts in, any idea how large a container I would need?

If you keep the box like we did you would be able to put every thing back in the box, It does not come with a container. If you need A container you would need about A two to three gallon container

Can the ferris wheel move both clockwise and counterclockwise?

HI there, thank you for your inquiry into the Knex 3-in-1 Amusement Park - the motor will only allow the ferris wheel to spin forward. Hope this helps you! Go to the Basic Fun website for more information if needed. - your friends at Basic Fun
