Will transparent PNG backgrounds stay transparent in the PDF?

Yes, the PDF will preserve transparency. If you want a white background, convert the PNG to have a white fill first.

What page size should I use?

A4 is best for printing. If you want each image to fill the page exactly, use fit-to-image or custom dimensions.
