Can I create resources (Textures, Vertex Buffers, etc) on one thread while another thread renders a scene using the same device?

I don't see any reason that you couldn't if you really wanted to, but unless you're on a machine that's really designed to handle multiple threads in that fashion, I don't think you'd get a very big performance increase.

It's not for performance. It's for a level loader. One thread loads resources, the other shows the 'loading' screen with a status bar that shows the status of the loader thread.

But if DirectX can handle it, then I guess I'm good to go.

Do I need to create the device with the D3DCREATE_MULTITHREADED flag?

Yes. The docs say that you get a slight performance loss, but It's completely unnoticible in every app I've written, so don't worry about it.
